WebShort-circuiting the waveguide of any shape, for example, rectangular, cylindrical, or circular, is one method of constructing a cavity resonator with a high-quality factor. In cavity resonators, the boundary walls are made of high-conducting metals and, thus, the electromagnetic energy is confined to the cavity. http://caisu1.ning.com/photo/albums/rectangular-and-circular-waveguides-ppt-background psychologist prince george
