Arbitrary order edge elements for electromagnetic scattering simulations using hybrid meshes and a PML

The use of arbitrary order edge elements for the simulation of two-dimensional electromagnetic scattering problems on hybrid meshes of triangles and quadrilaterals is described. Single-frequency incident waves, generated by a source in the far eld, are considered and the solution is determined in the frequency domain. For numerical simulation, the solution domain is truncated at a nite distance from the perfectly conducting scatterer and the non-re ecting boundary condition at the truncated boundary is imposed by the use of a perfectly matched layer (PML). Several examples are included to demonstrate the performance of the proposed procedure
