11. what is waveguide cutoff frequency , guide wavelength , phase velocity , group velocity , propagation constant
Lets explain cutoff frequency , guide wavelength , group velocity , phase velocity and propagation constant of a waveguide. Cutoff frequency : Cutoff frequency is the frequency below which attenuation occurs and above which propagation takes place.Each mode have a specific cutoff frequency. For...
