Microwave phase velocity
Web9 mei 2024 · Phase velocity is the speed at which a point of constant phase travels as the wave propagates. 1 For a sinusoidally-varying wave, this speed is easy to quantify. To … WebThe phase velocity of microwaves traveling inside a wave guide (a square pipe used in microwave plumbing) is typically larger than c. This is because there is a cavity resonance in the wave guide at a slightly higher frequency which elevates phase velocities on its upper frequency-slope. Does ...
