On percolation and circular Bragg phenomenon in metallic, helicoidally periodic, sculptured thin films
On percolation and circular Bragg phenomenon in metallic, helicoidally periodic, sculptured thin films
The concept of local homogenization is invoked in the visible and the sub-visible frequency regimes to estimate the permittivity dyadics of a thin-film helicoidal bianisotropic mediums (TFHBMs)~---~a canonical class of sculptured thin films with helicoidally periodic microstructure~---~made of a metal. Examination of the components of the permittivity dyadics, as well …
