A rectangular waveguide is to be constructed for single-mode operation at 3 GHz. The waveguide must be designed so that this operating frequency is 20% higher than the cutoff frequency of the lowest mode, and, at the same time, is 20% lower than the cutoff frequency of the next higher mode. The waveguide will be filled with a dielectric material with relative electrical permittivity of 2. Determine the cross-sectional dimensions, a and b, of the waveguide. Answer: 4.2 cm x...

A laser can be made by placing a light source in an optical resonant cavity which has two highly reflective flat mirrors at its ends. Light produced by the source will reflect back and forth from the end mirrors and so produce standing waves. Assume that the mirrors at the ends of the cavity are nodes of the standing wave pattern. (a) What are the frequencies of the normal modes of the cavity in terms of the distance L between...
