Polarization-universal rejection filtering by ambichiral structures made of indefinite dielectric-magnetic materials
Polarization-universal rejection filtering by ambichiral structures made of indefinite dielectric-magnetic materials
An ambichiral structure comprising sheets of an anisotropic dielectric material rejects normally incident plane waves of one circular polarization (CP) state but not of the other CP state, in its fundamental Bragg regime. However, if the same structure is made of a dielectric-magnetic material with indefinite permittivity and permeability dyadics, …
