Boundary-integral calculations of two-dimensional electromagnetic scattering in infinite photonic crystal slabs: Channel defects and resonances

SIAM JOURNAL ON APPLIED MATHEMATICS, 62(6), 2129–2148.

By: M. Haider n, S. Shipman & S. Venakides

author keywords: EM scattering; photonic crystal; photonic bandgap; channel defect; boundary integral; boundary element method; Ewald representation; resonances
TL;DR: The numerical implementation of a boundary-integral formulation of 2D electromagnetic scattering is refined by exploiting separability in the Green's function to evaluate the far-field influence more efficiently and the resulting cost savings in computing and solving the discretized linear system leads to an accelerated method.

Finite time-horizon risk-sensitive control and the robust limit under a quadratic growth assumption
