The post-wall waveguide, also called laminated waveguide or substrate integrated waveguide, has received a growing attention because of their promising applications to planar circuit components operating in the microwave and mm-wave frequency range. In this paper, we shall present a novel semi-analytical approach for analyzing the post-wall waveguide using the concept of two-dimensional photonic crystal waveguides. The fundamental properties of the TE{10} mode such as the propagation constant, the equivalent width, the cutoff frequency, and the leakage loss are discussed.
