Authors: Fisanov V. V.

Annotation: Plane electromagnetic waves in an isotropic absorbing chiral medium (chiral metamaterial) are considered. The Tellegen’s system of constitutive relations with complex values of dielectric permittivity, magnetic permeability and chirality parameter is applied. A distinction is made between the forward and backward evanescent normal waves of left and right circular polarizations by introducing a special parameter – a wave type identifier. Analytical expressions for real and imaginary parts of wave numbers and wave impedance of homogeneous normal waves are presented.

Keywords: wave impedance, wave number, wave type identifier, backward normal waves, forward normal waves, complex material parameters, dissipative losses, metamaterial, isotropic chiral medium
