Localized function method for modeling defect modes in 2-D photonic crystals
TLDR
In this paper, a vector treatment of electromagnetic modes localized at defects in two-dimensional (2D) photonic crystals is presented. But the method represents the fields in terms of orthogonal functions localized at the defect and is a fully vector treatment.Abstract:
We present a novel, general, and numerically efficient treatment of electromagnetic modes localized at defects in two-dimensional (2-D) photonic crystals. The method represents the fields in terms of orthogonal functions localized at the defect and is a fully vector treatment.read more
