Guided wave propagation in a parallel-plate waveguide with Kronig-Penney morphology is analyzed. Modes in the photonic band-gap (PBG) structure can be classified as either transverse electric or transverse magnetic with respect to the propagation direction. Above the modal cut-off frequencies, band gaps exist where propagation is forbidden. The locations and the widths of the band gaps depend on modal order, waveguide height, and the permittivity contrast and relative volumetric proportion of the two materials constituting the unit cell of the PBG structure.
