In this Letter a hybrid approach combining the finite‐element method and the method of lines is presented for solving the scattering problems of irregular geometry and inhomogeneity. In this approach, the FEM is used to treat the region with complicated geometry and inhomogeneous material profile, and the MoL acts as a radiation boundary condition for the FEM. The MoL can also treat layered regions. Because of the flexibility of the FEM and the semianalytical nature of the MoL, the flexibility, efficiency, and accuracy of these two methods are maintained. © 2002 Wiley Periodicals, Inc.
