Abstract
A physically realizable electromagnetic absorber that is constructed from a time-derivative Lorentz material (TD-LM) model for the polarization and magnetization fields is used to define an absorbing boundary condition (ABC) for the finite-difference time-domain method. This Maxwellian ABC is shown to have performance characteristics that are comparable to the non-Maxwellian-Berenger (see J. Comput. Phys., vol.114, p.185-200, Oct. 1994) perfectly matched layer (PML) ABC.Keywords
