Abstract
In this paper we present the wave propagation method for the retrieving of effective properties of media with circularly polarized eigenwaves, in particularly for chiral metamaterials. The method is applied for thick slabs and provides bulk effective parameters. Its strong sides are the absence of artificial branches of the refractive index and simplicity in implementation. We prove the validity of the method on three case studies of homogeneous magnetized plasma, bi-cross and U-shaped metamaterials.

Summary
Chiral metamaterials (MTMs) attract a lot of attention nowadays due to their promising properties. Effective parameters of chiral metamaterials are retrieved with a method based on inversion of reflection and transmission spectra [13,14,15], so we will refer to it as the standard method (SM). We use case studies of a homogeneous gyrotropic medium, bi-cross MTM and U-shaped MTM, all having eigenmodes as right-circular polarized (RCP) and left-circular polarized (LCP) waves. These examples serve to illustrate the WPRMC capabilities
