Sweep Frequency Heating based on Injection Locked Magnetron

Sweep Frequency Heating based on Injection Locked Magnetron

Conventional microwave heating has serious problems such as non-uniform heating and low efficiency. A novel magnetron microwave sweep frequency heating method is proposed to improve microwave heating uniformity. In this method, the frequency-sweeping signal is injected into the magnetron by the inje...
