Efficient mesh truncation techniques for the solution of Maxwell's equations using the finite-difference time domain method
… to open region radiation problems requires the truncation of the infinite domain down to a finite-sized domain amenable to numerical simulation. The accuracy of the solution and the computational expense required to attain the solution are dependent on the method used to simulate the infinite …

A Higher-Order Finite Element Method for Computing the Radar Cross Section of Bodies of Revolution
… to improve the performance of the FEM code. The mesh is truncated using two methods. The first method is the perfectly matched layer (PML). This method has a number of parameters that must be optimized to obtain good results. Furthermore, the PML must be kept a reasonable distance away from the …

Unified conformal/nonconformal domain decomposition methods for solving large-scale multi-region electromagnetic problems
… method to accommodate more flexible interface meshes, to achieve faster convergence of the global interface problem, and to reduce numerical errors caused by the truncation boundary. First, two nonconformal FETI-DP methods are formulated, both of which implement the Robin-type transmission …
