ABSTRACT
The possibility of eliminating the electromagnetic reflection of a plane wave from a perfect conductor by coating a homogeneous layer of a bianisotropic medium is studied. It is shown that the uniaxial chiral-omega medium is a natural choice for such a reflectionless coating at a fixed frequency in the normal incident case. The condition for zero reflection is derived. Numerical results show that a uniaxial omega coating can give more effective anti-reflection results than an isotropic conducting anti-reflection coating and an isotropic dielectric (or magnetic) anti-reflection coating.
