Abstract
ABSTRACTThe two‐dimensional electromagnetic scattering properties from multilayer rough surfaces with an object buried were studied in this article by the finite element method (FEM). When FEM is applied to analyze an open‐space scattering problem and an artificial boundary needs to be built to truncate the computational domain. The perfectly matched layer (PML) has been proved to be an accurate boundary condition in the electromagnetic scattering problems. It is widely used in the electromagnetic simulations for limited objects. However, there are few articles provided to deal with the scattering problem of the multilayer rough surfaces. In this letter, the modeling of multilayer rough surfaces with an object buried is presented, and the application of FEM and PML is provided in detail. The method is validated by the method of moments (MoM), and some numerical results are provided to discuss the scattering properties. © 2016 Wiley Periodicals, Inc.
