TLDR
In this article, the authors investigated the transmittivity of a bull's eye grating using the plane wave expansion method and optimized the parameters of the grating at 1550 nm.Abstract:
We investigated the transmittivity of a bull's eye grating using the plane wave expansion method. The parameters of the grating were optimized at 1550 nm. The grating has annular grooves with alternating layers of aluminum and air. The dispersion relation was obtained by expressing Maxwell's equations in cylindrical co-ordinates and solving the eigenvalue problem. We observe flat bands for frequencies below plasma frequency (ω p ). COMSOL simulations were used to validate the eigenfrequencies at k→ 0 in the band diagram.read more

Photonic band structures of two-dimensional systems containing metallic components
TL;DR: This work calculates the photonic band structure for electromagnetic waves of E and H polarization propagating in a system consisting of an infinite array of identical, infinitely long, parallel, metal cylinders of circular cross section, embedded in vacuum, whose intersection with a perpendicular plane forms a simple square or triangular lattice.

TL;DR: From the results, it is possible to give a simple recipe to design a bull's eye structure with optimal transmission properties and several parameters are seen to be interlinked and scale laws emerge.
