Abstract

This paper presents a general deterministic optimization procedure to compute the spatial repartition of material property-dissipative and nondissipative part-which minimizes physical or numerical reflection in physical and Maxwellian absorbers. The reflection performances of particular absorbers are compared from many points of view and deeply analyzed. The obtained results can usefully guide the designer in the choice of a particular absorber for the treatment of practical or numerical applications
