WebIn RF and microwave circuits, the cut-off frequency is a significant specification for waveguides. In a rectangular waveguide being used to transfer energy, the rectangular waveguide cut-off frequency determines when the waveguide becomes obsolete, which is whenever it reaches below the cut-off frequency. A similar condition applies to … WebHoje · The group velocity v g of light with frequency ω in an optical waveguide is given as: (2) v g = d z d t = Δ ω Δ k = d ω d k, where k is the wavevector along the waveguide. Moreover, (3) v g = v p + k d v p d k = v p − λ d v p d λ = c n (1 + λ n d n d λ), where v p is the phase velocity of light, and n g is the group index. imss afil 01 editable
