摘要
A semianalytical finite element method (FEM) is proposed for analyzing propagation of electromagnetic waves in stratified media. Conventional finite elements are used to discretize the cross-section of a layered structure, and a Riccati equation-based integration scheme is used to handle the longitudinal direction with a very high precision. This semianalytical FEM is easy to implement. Numerical examples demonstrate that the proposed method has high efficiency and accuracy.
