  • Patent number: 7381932
    Abstract: A quasi-optical material treatment apparatus includes a first mirror and a second mirror. The first mirror is arched, and has a focal point in a chamber distance, and a coupling port to receive a high power microwave from an external microwave source that travels along the chamber distance to output a strong field microwave beam. The second mirror and the first mirror jointly form a quasi-optical action chamber and are movable relative to each other to adjust the total chamber distance between the two. A material to be treated may be moved through a focusing zone (about one wavelength of the strong field microwave beam) of the strong field microwave beam to be treated rapidly and evenly.
