TLDR
In this article, a reconfigurable all dielectric FSS based filter has been proposed which exhibits band-pass and band-stop filtering actions in the same band by tailoring the constructional parameters mechanically without changing the dimensions of the unit cell.Abstract:
A reconfigurable all dielectric FSS based filter has been proposed which exhibits band-pass and band-stop filtering actions in the same band by tailoring the constructional parameters mechanically without changing the dimensions of the unit cell .Band-stop operation is conceived from 3.3-6.8 GHz by conglomerating four hexagonal prisms made of AD410 with a cuboidal structure made of AD1000L.The removal of the hexagonal prisms makes the cuboidal structure function as a band-pass filter from 3.8-7.4 GHz. Switching between bandpass and bandstop filtering action is thus realized in the frequency range 3.8-6.8 GHz.read more

Design and Optimization of 3-D Frequency-Selective Surfaces Based on a Multiobjective Lazy Ant Colony Optimization Algorithm
TL;DR: It will be shown that the MOLACO algorithm generates several innovative and unintuitive unit cell geometries with a single-zero, single-pole response, less than 1% shift from center frequencies and 3 dB transmission bandwidths between 6%–12% for angles of incidence up to 80° in TE and TM polarizations.

TL;DR: In this paper, the propagation of periodic arrays of dielectric slabs in the direction transverse to that of periodicity is studied as a function of the prescribed phase delay per period for two polarizations.
