T1 PLANAR CHIRAL IRISES IN A SQUARE WAVEGUIDE AND "OPTICAL ACTIVITY" MANIFESTATIONS JF Radio Physics and Radio Astronomy JO RPRA YR 2011 FD 2011-07-07 VO 2 IS 3 SP 255 OP 264 K1 optical activity K1 chirality K1 waveguide K1 iris AB A square waveguide with a four-slot iris possessing four-fold symmetry of rotation and complementary simple elements is addressed to analyze the spatial spectrum of modes exited in the reflected and transmitted fields. The cross-polarized field was identified behind the waveguide object. The reasons for its appearance, revealed and examined, enable the obtained conclusions to be extended to the "optically active" metamaterials built around periodically arranged planar chiral elements.
