Metamaterial slabs and realization of all-type filter characteristics: Numerical and analytical investigations

Abstract

Sevgi, Levent (Dogus Author)Studies towards understanding and the use of metamaterials (MTM) have risen in electromagnetic engineering. This article presents analytical and numerical investigations of filter characteristics of MTMs in two-dimension (2D). Numerical investigations are based on finite difference time domain (FDTD) simulations, analytical formulations belong to a plane wave excitation of multi-slab structures. It is shown that a three layer structure with different combinations of MTMs and non-MTMs may be used to realize all four types of filter characteristics
