Abstract

In a method and apparatus for matching a microwave heater to reduce the microwave energy reflected by the load, microwave energy from a microwave source 6, 7 is supplied to a treatment chamber 3 by a hollow waveguide 8, 9 of square or rectangular section, a directional coupler 16, 17 in the waveguide 8, 9 prevents reflected energy returning to the source 6, 7 and directs it to an absorption means, a detector 18 being provided at the absorption means to measure the reflected energy. The detector output, via control means 19 to 24, controls motors M1 to 3 to operate tuning pins 13, 14, 15 in the waveguide 8, 9, the motors M1 to 3 having different operating speeds. <IMAGE>
