S. Venakides et al., Boundary integral calculations of two-dimensional electromagnetic scattering by photonic crystal Fabry-Perot structures, SIAM J A MA, 60(5), 2000, pp. 1686-1706
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.
