## Abstract Verifying the duality of electric and magnetic fields using the nonstandard FDTD method is important for far‐field calculations using the equivalence principle and for the reduction of reflection from boundaries of different size lattices. In this paper, the duality of the fields using

This paper shows that evanescent waves may be so strongly absorbed within perfectly matched layers (PML) that they cannot be properly sampled by discrete methods. With the "nite-di!erence time-domain (FDTD) method, this results in a severe numerical re#ection from vacuum}PML interfaces. A similar re
