Cut off wavelength in waveguide
WebMay 9, 2024 · Since waveguides are normally intended for the efficient transfer of power, it is important to know the criteria for a mode to be cut off. Since cutoff occurs when (k ( m, n) z)2 < 0, cutoff occurs when: ω2μϵ > (mπ a)2 + (nπ b)2 Since ω = 2πf: f > 1 2π√μϵ√(mπ a)2 + (nπ b)2 = 1 2√μϵ√(m a)2 + (n b)2 Webλg = wave length of the electromagnetic waves inside the waveguide. f = frequency in free space. c = velocity of electromagnetic wave in free space. fc = cut off frequency.
