Abstract:

 

We propose a methodology based on linear embedding via Green's operators (LEGO)  and the eigencurrent expansion method (EEM)  to  efficiently deal with and locally  optimize 2-D electrically large  electromagnetic band-gap (EBG) structures. In LEGO terminology, the composite EBG structure is broken up (diakopted) into   constitutive elements called bricks'' that we characterize through scattering  operators by invoking Love's equivalence principle, while, at the same  time, the electromagnetic interaction among the bricks  is captured by transfer operators. The resulting electromagnetic problem is then succinctly formulated through an integral equation involving  the  total  inverse scattering operator S-1 of the  structure.  To perform local optimization, the formulation of the problem allows for  variations of the electromagnetic  properties and the  shape of a set of objects  in  the EBG structure with respect to  those  of the others, thereby allowing us  to tune a compact  designated  domain  within a large one. Finally, the method of moments and the EEM  are applied to achieve  a considerable  reduction in memory use for the overall problem.
