Using the multipole approach we considered the dynamics of plasmonic oscillations in asymmetric double-wire metamaterials. Magnetization of materials is defined by the position of the largest wire with respect to the exciting electric field.
The combination of high-field physics with nano-plasmonics has proven to be feasible in producing high harmonics of intense laser radiation from noble gases, assisted by the field-enhancement effect in the proximity of metallic nano-antennas. However, the intensity region where harmonics can be generated without irreversible damage to these delicate structures is rather narrow. We explore the damage...
Metamaterials are artificial media that allow tailoring the macroscopic properties of light propagation by a careful choice of nanoplasmonic inclusions it is made of. A simple and versatile analytical model describing propagation of electro magnetic waves in metamaterials is suggested. The model is based on the secondary averaging procedure in full analogy with the ordinary one accepted for Maxwell...
Homogenization of optical metamaterials is one of the fundamental problems of electrodynamics of composite materials. Here the homogenization approach using multipole expansion is analysed and compared with the phenomenological one. Applications of the developed model for different structures and various phenomena are presented.
We describe the different optical responses of geometrically related metamaterials with an analytical method based on multipoles. Metamaterials affecting the polarization eigenstates or mimicking EIT-like phenomena can be understood and explained on simple analytical grounds.
This article investigates the multipole expansion approach in order to describe analytically linear and nonlinear optical properties of metamaterials. It is shown that especially the consideration of electric quadrupole multipoles (not only the magnetic dipole one) is required by basic principles and provides the possibility to adequately analyse an effective magnetic material response. To motivate...
An alternative way to determine the dispersion relation and the effective material parameters is presented. The introduced model can be applied to treat the double wire as well as the split ring resonator geometry, while the first one is presented in this paper. The approach combines the electric and magnetic multipole expansion of a single structure to describe the propagation properties of the respective...
