Webdimensions) and travels in the z-direction. For example, the cross-section of a rectangular waveguide is shown below. Unfortunately, the exact modes of such 2D waveguides are not as easy to complete as those of slab waveguide. The modes are neither TE nor TM. All modes have a small component of E and H fields in the direction of propagation. The E WebThe numbers m and n correspond to the number of wave halves present in the waveguide walls of dimensions a and b, respectively. The mode index is applicable to the two modes of wave propagation possible in a rectangular waveguide (TE and TM mode). Every combination of m and n defines a mode in a rectangular waveguide except (0, 0). WebSelf-consistency condition: the phase shift between the two waves must be 0 or a multiple of π 2. A wave should reproduce itself after each round trip, otherwise they will have phase shift not equal to a multiple of 2π.
