Packet suppression of a leakage of microwave power from industrial heating systems via the higher modes of open waveguide ports
Keywords:microwave heating, waveguide filter, bandstop filter, safety
AbstractA waveguide bandstop filter intended for an open port of an industrial heating system is numerically modeled. The filter was designed to suppress a leakage of microwave power from a magnetron operating the frequency of 2.45 GHz. A modification the filter providing an improved suppression of a power leaking via higher waveguide modes is proposed. A reduced leakage level is obtained without enlargement of the microwave filter.
