 Nanostructered  plasmonic metamaterials

Nanostructured metal-dielectric interfaces can exhibit a number of unusual optical properties due to the strong electromagnetic enhancement they can provide via the excitations of plasmon resonances. This makes metallic nanostructures very attractive for a wide range of applications from molecular spectroscopy and sub wavelength imaging, to real-time chemical and biological sensing. The resonance behaviour of surface plasmons strongly depends on the structural morphology and dielectric environment, thus providing an effective way for tailoring the optical properties. Recent advances in nanotechnology have enabled the formation of elongated nano-inclusions in the form of wires, rods and rings, enabling highly confined and controlled plasmonic resonances. Furthermore, we have demonstrated that arrays of coupled rods can support two principle resonance modes: a symmetric electric dipole mode and an anti-symmetric mode generating a magnetic-like response. These systems have attracted much interest as metamaterials with a negative refractive index at optical frequencies for realising sub wavelength imaging. However, substantial losses due to resonances are obstructive for imaging applications. We propose to utilise the resonance properties of Au & Ag coupled nano-rods for optical sensing, where the loss factor imposes no restrictions, thus offering a number of advantages for sensing applications, including sharp resonances, active spectral tunability by changing the coupling spacing, and strong anisotropy with respect to light polarisation. The spectra are of a resonance type.  For parameters: rod’s cross section of 40 nm square, inter pair distance of 100 nm and a length of 300 nm, and matrix permittivity 1.3 the main plasmon resonance is near 900nm (infrared). The resonance wavelength can be tuned by changing the pair distance d. We then propose to use a ferroelectric or piezoelectric thin film (for example, Lithium Niobate) with relatively low permittivity for altering d. Our simulation studies demonstrated that the resonance wavelength in the pair with d = 40 nm will shift to 790nm (from 900nm), with all other parameters fixed. This property is very beneficial for sensing applications providing an additional mechanism of tuning the resonance by altering the structural parameters and designing the sensing channels to operate at different wavelengths. The estimated sensitivity of the reflection spectra to the refractive index change is more than 800 nm/RIU, which is a few times larger than those reported for other nanostructure designs, benefiting from multiple resonances and active tuning.

The main results are:

·         Theory of effective permittivity in coupled nano-rod, nano-ring systems

·         Effects of impedance matching

·         Optimisation of nano-rod structures for sensing applications

Magnetoimpedance (MI) effect  and  sub nano Tesla magnetic  sensors

The discovery of the MI effect in 1994 (independently by L. V. Panina, K. Mohri , Nagoya University, Japan; R.S. Beach and A.E. Berkowitz, Alabama Research Centre, USA)  had a strong impact on the development of magnetic sensors, offering miniature, highly sensitive, and quick response elements. In soft magnetic wires with circumferential anisotropy  the electric  impedance change (MI ratio) can be as high as 600 % in the MHz band and 50-100% at GHz frequencies subjected to small magnetic fields. Furthermore, multilayered thin-film structures have been proposed to improve the MI performance in miniature elements. We have developed physical concepts of MI in amorphous microwires and magnetic/metallic multilayers including effects of magnetic anisotropy, asymmetric MI (AMI), off-diagonal MI, and enhancement of MI ratio in multilayered films. A software package is available for impedance modelling in systems of cylindrical and film shapes with arbitrary magnetic anisotropy.  Our experimental results (and other groups) have proven very high sensitivity of MI for excitation frequencies up to few GHz, and demonstrated realisation of AMI in systems with a spiral type of anisotropy. We have proposed an advanced high performance sensor design based on  pulse and sinusoid excitation techniques.  This has led to the development of a low cost, portable sensor capable of measuring a linear response in the field range of ± 1Oe to a resolution of 0.1µ Oe.

 The main results include:

·         Theory of MI  and asymmetrical MI in microwires and multilayer films

·         Asymmetrical magnetoimpedance in wires with helical anisotropy and  in films    with     spiral anisotropy

·         Experimental methods of impedance measurements

·         Off-diagonal magnetoimpedance in wires and sandwich films

·         High resolution magnetic sensors

·         Stress-impedance in wires at GHz frequencies

Magnetic  wire based metamaterials

In general, artificial materials with conducting fibres present a considerable interest since their dielectric response characterized by an effective permittivity exhibits various dispersive behaviours. These materials can be represented by arrays of continues wires as in (a) or composites with randomly or periodically oriented wire pieces as in (b).  The first type of wire-composites has characteristic features of a plasmonic response to radiation, but with the plasma frequency in the GHz range.  In the second case, finite-wire inclusions behave as electric dipole scatterers which experience a resonance at half wave-length condition. In natural dielectrics, the electrical polarization is associated with either induced or permanent dipole moments of molecules and atoms. At microwave frequencies the molecular dipole orientation mechanism gives the main contribution to the dispersion of the permittivity which obeys a Debye relaxation. The charge oscillation mechanism and associated resonances become important at much higher frequencies: infrared for the ion polarization and ultraviolet for the electron polarization. The presence of thin conducting wires constrains the electron movement with the associated resonances determined by the geometrical parameters of the wires. Then, the frequency dispersion can be established in a specific GHz frequency band with the characteristic frequencies determined by the spacing between the wires b or the wire length l.  For thin wires with the diameter in the range of the skin penetration depth, the wire impedance introduces damping into the current resonances. This results in another striking property of the composites with magnetic wires that the permittivity dispersion may be strongly dependent on the wire magnetic structure owing to the MI effect. For example, increasing the wire impedance by establishing the magnetisation along the axis with an external magnetic field broadens the resonance band, decreases the reflection amplitude  and may open  a bandpass. Depending on the magnetic anisotropy in wires, tuning can be realized with both magnetic field and stress. It is foreseen that  MI-wire composite materials could be suitable for large scale applications, in particular, for free space filters in secure wireless systems and for microwave nondestructive testing and control in civil engineering.

Main results:

·         Theory of effective permittivity in magnetic wire composites: cut-wire composites and continuous wire arrays

·         Stress-effects in magnetic wire composites

·         Experimental results on scattering from magnetic-wire composites

 Magnetisation processes and dynamics in microwires and thin films

 Amorphous magnetostrictive wires exhibit very rapid bistable magnetization reversal  (large Barkhausen jumps). This property makes them unique for applications in security sensors and remote coding and identification. The magnetic bistability is  determined by an axial domain structure that exists in as-cast positive magnetostrictive wires  and can be perfected  by various annealing methods. The absence of the magnetocrystalline anisotropy means that the anisotropy and therefore the domain structure are determined by the balance between the magnetoelastic and magnetostatic (shape) contributions. We demonstrate that some magnetic properties of amorphous wires can be locally and controllably tuned by Ar laser processing due to the formation of magnetic heterostructures. This can be of great interest for application of amorphous wires as magnetic labels and tags.  

The main results include

 ·         Dynamical hysteresis in positive magnetostrictive wires

·         Circular bistable hysteresis in wires with a circumferential anisotropy

·         Formation of hetaramagnetic structures by localized laser annealing

·         Development of interrogation systems for labeling applications
