Propagation in bianisotropic media — reflection and transmission

Spherically symmetric inhomogeneous bianisotropic media: Wave propagation and light scattering

Determination of the effective constitutive parameters of bianisotropic metamaterials from reflection and transmission coefficients.

We propose a method to retrieve the effective constitutive parameters of a slab of bianisotropic metamaterial from reflection and transmission coefficients (or scattering parameters). In our retrieval method, only the scattering parameters in one propagation direction are used. Analytical inversion equations are derived in order to retrieve the effective parameters of the permittivity, permeabi...

Extended discrete dipole approximation and its application to bianisotropic media.

In this research we introduce the formalism of the extension of the discrete dipole approximation to a more general range of tensorial relative permittivity and permeability. Its performance is tested in the domain of applicability of other methods for the case of composite materials (nanoshells). Then, some early results on bianisotropic nanoparticles are presented, to show the potential of th...

Reflection and Transmission of Plane Waves at Micropolar Piezothermoelastic Solids

The present investigation analysis a problem of r­­­eflection and transmission at an interface of two micropolar orthotropic piezothermoelastic media. The basic equations and constitutive relations for micropolar orthotropic piezothermoelastic media for G-L theory are derived. The expressions for amplitude ratios corresponding to reflected and transmitted waves are derived analytically. The eff...

Reciprocity principle in bianisotropic composite media (Microscopic approach)

The paper deals with reciprocity relations in bianisotropic electromagnetic materials. Conditions for reciprocity are expressed and discussed in connection with macroscopic and microscopic level of consideration and with space-time symmetry properties of media. Newly is the connection between microscopic and macroscopic treatment to reciprocity theorem analyzed namely with respect to composed b...
