The Method of Auxiliary Sources (MAS) is used to study the torus form concave-convex hollow metallic voluminous resonator. Such resonators have wide application in high frequency radio-electronics. Using the proposed method it is possible to find all eigen frequencies of the voluminous resonators and study the structure of the eigen resonant fields.
