Impedance of waveguide
A propagation mode in a waveguide is one solution of the wave equations, or, in other words, the form of the wave. Due to the constraints of the boundary conditions, there are only limited frequencies and forms for the wave function which can propagate in the waveguide. The lowest frequency in which a certain mode can propagate is the cutoff frequency of that mode. The mode with the lowest cutoff frequency is the fundamental mode of the waveguide, and its cutoff freque… http://swedishchap.weebly.com/uploads/5/2/3/4/5234043/waveguide_notes_2_autosaved.pdf

The coupling impedance of CV-FWG is about 3.2 times higher than that of FWG. Figure 11 shows the losses of the CV-FWG and FWG. Compared with FWG, the loss of CV-FWG is increased by 31.6% at 81 GHz and 35.6% at 86 GHz.
Witryna9 maj 2024 · The speed of a signal within a rectangular waveguide is given by the group velocity of the associated mode (Equation 6.10.15 ). This speed is less than the speed of propagation in unbounded media having the same permittivity and permeability. Speed depends on the ratio fmn / f, and generally decreases with increasing frequency for …
