Abstract

The T-matrix method is used to model semicircular channels filled with chiral materials in a conducting plane. The coupling of both TM and TE polarizations is represented explicitly. Addition theorems in half space are derived and used to take account of the multiple scattering of parallel channels. The boundary conditions are checked for chiral channels to verify the algorithm proposed. Co- and cross-polarization effects of chiral materials are investigated by varying several physical and geometrical parameters of the parallel channels.
