Higher Order Finite-difference Frequency-domain Analysis of Two-dimensional Photonic Crystals with Arbitrary Shapes

摘要：

A higher order finite-difference frequency-domain (FDFD) method is proposed for the analysis of the band diagrams of two-dimensional (2-D) photonic crystals (PCs). This improved formulation is based on Taylor series expansion (TSE), local coordinate transformation (LCT), boundary condition matching (BCM), and the generalized Douglas (GD) scheme. The fourth-order convergence can be achieved with little additional computational cost compared with that of a second-order scheme. This proposed scheme can deal with piecewise homogeneous structures with slanted dielectric interfaces.
