Abstract
A method and a device for controlling the feeding of microwave power through a waveguide in a microwave heating appliance. A conductor member (31) is movably arranged in the waveguide (32) between an inactive position with no appreciable effect on the feeding of microwave power and an active, resonant position, in which resonance currents are generated, which give rise to a changed mode pattern which acts upon the transportation of the microwave power through the waveguide. The member (31) is preferably an elliptic ring member. In this connection, repositioning is effected by means of controlled rotation about an ellipse axis.
