Extension Of The Contour Integral Method For The Modeling Of Te Scattering In Two-Dimensional Photonic Structures Using The Duality Principle

The Contour Integral Method (MI) is a numerically efficient modeling technique for planar or infinitely extended two-dimensional (2-D) structures. In the optical regime, the CM has already been adapted and applied for the modeling of TMOZ-mode scattering in photonic crystals. In this work the dual case of TEOZ-mode scattering is addressed. Making use of the duality principle, expressions for the behavior of the TEOZ-mode can be derived from the system matrices associated with the TMOZ-mode. This allows to reuse use formulas and program code written for the TMOZ-mode with minimal adjustments. The results are validated by comparison to full-wave simulations.
