Abstract

Electromagnetic waveguides Finite difference methods Finite element methods Moment methods Periodic structures Time domain analysis
We present a new numerically efficient and accurate technique for the analysis of three-dimensional arbitrarily shaped periodic structures for arbitrary incidence angles. The proposed method does not suffer from the stability issues encountered in the Finite Difference Time Domain (FDTD)/Periodic Boundary Condition (PBC) algorithm, which can become unstable and computationally intensive for wide angles of incidence.
