Abstract
A physically realizable electromagnetic absorber that is constructed f rom a time-derivative Lorentz material (TD-LM)) model for the polariza tion and magnetization fields is used to define an absorbing boundary condition (ABC) for the finite-difference time-domain method, This Max wellian ABC is shown to have performance characteristics that are comp arable to the non-Maxwellian-Berenger perfectly matched layer (PML) AB C.
