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 finitedifference time-domain method. This Maxwellian ABC is shown to have performance characteristics that are comparable to the non-Maxwellian-Berenger perfectly matched layer (PML) ABC.
