Abstract

The tilt angles and the ellipticities of transmitted and reflected plane waves are shown to be different from those of plane waves normally incident on slabs of dissipative dielectric thin-film helicoidal bianisotropic mediums (TFHBMs). These slabs can therefore function as transformers of vibration ellipses in optical circuits. The transformation properties can be engineered by proper selection of geometric parameters, and can be dynamically controlled by varying the concentration of appropriate fluids in the porous TFHBMs. The true circular dichroism and an apparent circular dichroism are shown to convey different types of information.
