Abstract—An approach is proposed for the physical realization of a perfectly matched layer (PML) at the open end of a waveguide is proposed. In addition, the paper proposes an extension of the concept of a physically realizable PML to suppress dispersive distortions: it is demonstrated that adapting PML principles enables the synthesis of a dispersionless interference PML antenna.
