Normalized frequency waveguide
WebAll waveguide systems are operated in a frequency range that ensures that only the lowest mode can propagate. If several modes can propagate simultaneously, one has no control over which modes will actually be carrying the transmitted signal. This may cause undue amounts of dispersion, distortion, and erratic operation. A mode with cutoff ...
