Abstract :
A compact and lightweight cavity with empty core and quasiuniform field distribution in the central region is described. In contrast with dielectric-loaded cavities only metallic losses are present. Thus the quality factor is reasonably high. An efficient and rigorous analysis method yielding the resonant frequencies and field distribution is presented. Theoretical results are compared with measurements.
