Abstract

Apparatus and method for applying microwave energy to a material in a resonant cavity. The Q of the cavity is reduced to broaden the bandwidth of the system by passing a portion of the microwave energy from the cavity through an iris plate to a dummy load positioned outside the cavity. Tuning stubs are provided to tune the cavity to resonance.
