WebThe TEM mode of propagation is the mode of propagation in coaxial lines, two-open-wire lines, stripline transmission lines, and parallel plate lines. In a non-dispersive medium with TEM propagation, the characteristic impedance and phase velocity remain constant. However, multiple dielectrics in coax and striplines lead to non-pure TEM modes. 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
