Question

Phase velocity and group velocity in yerms of cutoff wavelength guided wavelength,freespace wavelength

Answer 1

Lets explain cutoff frequency , guide wavelength , group velocity , phase velocity and propagation constant of a waveguide. ... Where ⋋0 is the free space ...

Answer 2

The guided wavelength and the phase constant are related by 2π/βg = λg, where βg is the guided phase constant and λg is the guided wavelength. 10. The phase velocity refers to a group of waves and the group velocity refers to a single wave.
