Abstract

A parallel plate waveguide structure configured to suppress parallel-plate waveguide modes is described. The electromagnetic material properties of individual layers disposed between the conductive plates of waveguide may be selected to allow an apparent stopband to form. Several physical examples of electromagnetic bandgap (EBG) structures are presented that are analyzed by full wave simulations and transverse resonance models.
