Boundary integral calculations of two-dimensional electromagnetic scattering by photonic crystal Fabry-Perot structures

We compute the transmission properties of two-dimensional (2-D) electromagn etic transverse magnetic (TM) waves that are normally incident on a Fabry P erot structure with mirrors consisting of photonic crystals. We use a bound ary integral formulation with quadratic boundary elements and utilize the E wald representation for Green's functions. We trace the frequencies of the Fabry Perot cavity modes traversing the photonic bandgap as the cavity leng th increases and calculate corresponding Q-values.
