WebSep 12, 2024 · In this way, we obtain the explicit formula for cut-off frequency: \[f_c = \frac{\phi}{h}. \label{6.15} \] Cut-off frequency depends only on the work function of the metal and is in direct proportion to it. When the work function is large (when electrons are … WebMay 9, 2024 · As noted in Section 6.1, the speed at which information travels is given by the group velocity vg. In unbounded space, vg = vp, so the speed of information is equal to the phase velocity in that case. In a rectangular waveguide, the situation is different. We find: vg = (∂k ( m, n) z ∂ω) − 1 = vpu√1 − (fmn / f)2.
WebA recent study (Hickey, Brett and D r u m - mond, 1962) has extended investigation of the temper- ature coefficient of the centre of lower cut-off (defined through the wavelength for which the transmission is 50 per cent) for seven other Schott sharp cut-off filters: the results demonstrate that there is a definite relationship between the ... WebMar 21, 2024 · cutoff wavelength 1. In detector technology, the long wavelength at which detector response falls to a set percentage (usually 20 or 50 percent). 2. In fiber optics, the shortest wavelength at which a fiber transmits in single mode. Below the cutoff several modes will propagate and the fiber is no longer single-, but multimode. 3.
