The Microwave Circuit The experimental circuit which has to date met with greatest favor consists of cavities coupled to input and output waveguides, as shown in Fig. 2. The grid, of course, is grounded directly to the cavity walls and separates the input cavity from the output cavity. An iris with its orifice.
