Distribution of Intrinsic Hybrid Modes in a Waveguide Structure Based on a Gradient Bianisotropic Metamaterial

Abstract

We solved the problem of propagation of plane waves in an artificial gradient chiral medium with an anisotropic chirality coefficient. We studied changes in the polarization vector of a normal wave, especially in the vicinity of the bifurcation point. The computational experiment proved that by varying the gradient parameters of a smoothly anisotropic meta-environment, it is possible to synthesize frequency-polarization-selective filters and polarization converters controlled by the given quality criterion.
