Electromagnetic Scattering by a Chiral Impedance Screen
In this paper the solvability of the direct electromagnetic scattering problem by an impedance screen in a chiral environment is presented. Time-harmonic electromagnetic plane waves in a chiral medium are considered as incident fields. These propagating fields are scattered by an obstacle which is a partially coated open surface \(\Gamma \), well known as the “screen”. Uniqueness results are proved using appropriate relations for Beltrami fields, and in addition, existence results are established by using a variational method in suitable functional space setting.
