Abstract

PURPOSE: To reduce the space factor by connecting a sub-waveguide in 3 dB on one end surface of a waveguide.
CONSTITUTION: A sub-waveguide 13 is connected on the narrow end surface of a heating waveguide 5 through a connection hole 14 having a length of λg/2 (1/2 of guide wavelength), providing the function of a launcher for connecting a magnetron 1. A movable short-circuit plate 15 is arranged at the position λg/4 far from the connection hole 14, and a material to be heated is inserted from the inlet 16 of the waveguide 5, so as to be retained at the central part of the waveguide 5 by a ridge 7. The waveguide 5 and the sub-waveguide 13 constitute a connector in 3 dB, and thus, the space occupied by waveguide system can be reduced by one-half of the conventional.
