1. An instrument for microwave-assisted chemical processes that avoids tuning discrepancies that otherwise result based upon the size and composition of the materials being heated, said instrument comprising:

  • a source of microwave radiation;

    a waveguide in communication with said source, with at least a portion of said waveguide forming an annulus with a rectangular cross section;

    a right cylindrical static cavity including a circular floor and a circular attenuator and immediately surrounded by said annular portions of said waveguide; and

    at least 3 slotted openings in the circumference of said annular waveguide that provide microwave communication between said waveguide and said static cavity and optimized coupling between microwaves from said source and materials being heated.
