Transmission and reflection of light normally incident on a layer of a medium with dielectric and magnetic helicities is studied. The axes of local tensors and and the helix axis are parallel to one another and perpendicular to the boundary surfaces. Jones matrices are constructed. Reflection and transmission coefficients, the rotation of the plane of polarization, and the ellipticity of polarization are calculated. Specific features of natural polarizations and the character of reflection and passage of waves with natural polarizations are studied.

Analytic expressions for the eigenvalues for the four-wave components at an oblique angle of light incidence inside a randomly oriented anisotropic magneto-optic dielectric medium are reported explicitly. In particular, these solutions are valid as long as the dielectric function tensor consists of a symmetric and an antisymmetric part. The normalized Jones reflection and transmission coefficients, i.e., the generalized ellipsometric parameters of homogeneously layered systems having nonsymmetric dielectric properties, are obtained immediately from a recently reviewed 4 ϫ 4 matrix approach. Our explicit solutions allow a future analysis of the generalized ellipsometric data of multilayered magneto-optic media regardless of the orientation of the material magnetization and crystalline axes and the angle of light incidence. Possible experimental thin-film situations are discussed in terms of generalized ellipsometric parameters and illustrated for birefringent free-carrier effects in heavily doped semiconductor thin films and for oblique magnetization directions in magneto-optic multilayer systems.

The light transmission through metallic films with different types of nano-structures was studied both theoretically and experimentally. It is shown, analytically, numerically and experimentally, that the positions of the surface plasmon resonances depend on nano-structural details. This leads to a strong dependence of the amplitude of the light transmission, as well as the polarization of the transmitted light and other optical properties, on those details. Two complementary situations are considered: a metal film with dielectric holes and a dielectric film with metallic islands. Two different possibilities for manipulating the light transmission are considered: One is based upon application of a static magnetic field (actually, this is equivalent to changing the nano-structure in a transformed configuration space), the other is based upon using liquid crystals as one of the constituents of a nano-structured film.

The major issue regarding magnetic response in nature-"negative values for the permeability μ of material parameters, especially in terahertz or optical region" makes the electromagnetic properties of natural materials asymmetric. Recently, research in metamaterials has grown in significance because these artificial materials can demonstrate special and, indeed, extraordinary electromagnetic phenomena such as the inverse of Snell's law and novel applications. A critical topic in metamaterials is the artificial negative magnetic response, which can be designed in the higher frequency regime (from microwave to optical range). Artificial magnetism illustrates new physics and new applications, which have been demonstrated over the past few years. In this review, we present recent developments in research on artificial magnetic metamaterials including split-ring resonator structures, sandwich structures, and high permittivity-based dielectric composites. Engineering applications such as invisibility cloaking, negative refractive index medium, and slowing light fall into this category. We also discuss the possibility that metamaterials can be suitable for realizing new and exotic electromagnetic properties.
Advances in Electromagnetics of Complex Media and Metamaterials

On the base of the exact solution of the boundary-value problem for artificial helicoidal media with local chirality we describe the reflection of electromagnetic waves on the periodic structure of medium as well as Fresnel's reflection from sample's boundaries. It allows to model the transmission and reflection of electromagnetic waves in dependence on the obtained parameters of artificial helicoidal medium and to design the device for polarization transformation. A possibility of the minimizing of size of a structure for transformations of the polarization state of electromagnetic waves is shown .

The fascinating optical properties of metamaterials and metasurfaces are intrinsically wave-vector (k) dependent and spatial dispersion effects induce a complex optical response. Here, Mueller matrix spectroscopic ellipsometry, providing both amplitude and phase information in the visible, is used in a large frequency and k-space range to characterize a plasmonic meander and assign the polarization effects to the microscopic plasmonic excitations of a metasurface. This leads to a fundamental physical insight into the optical properties of the plasmonic meanders: the effect of closed-film resonant coupling is used for large polarization rotation and high transmission, and multiple optical functions are created within one compact design, which cannot be obtained by any natural crystal.
Angular resolved effective optical properties of a Swiss cross metamaterial
Applied Physics Letters, 2009
We both experimentally and theoretically study the effective optical properties of a Swiss cross metamaterial at oblique incidence and reveal their angular dependence. Almost perfect agreement between measured and calculated data is achieved. We show that the spectral and angular domains of negative refraction as well as its strength depend strongly on the light's propagation direction and polarization state. Our results clearly indicate that a description of a Swiss cross metamaterial in terms of effective material parameters is impossible.
