Abstract

A volatiles analyzer is disclosed that includes a source of microwave radiation that can selectively produce at least one predetermined frequency of microwave radiation. A cavity is in communication with the source. The walls of the cavity form a twelve faced polyhedron in which eight faces form a regular octagon and having two faces that are both non-parallel and non-perpendicular to the eight faces of the regular octagon. The polyhedron focuses microwave energy of the predetermined frequency on a balance pan while supporting a plurality of TM and TE modes in the cavity.
