ABSTRACT:
A microwave applicator for uniform or profiled heating of materials with microwave energy. A hollow rectangular waveguide is provided with an array of resonant slots communicating through the wall of the waveguide. The slots are spaced out from the center line of the wall by varying amounts in order to selectively couple energy out of the waveguide. The slots are provided in pairs, individual slots and slot pairs being longitudinally separated by multiples of three-quarters waveguide wavelength distance to improve the efficiency of energy coupling out of the waveguide.
