  • Method for improving uniformity of electromagnetic field inside static microwave resonant cavity
    Patent number: 12289816
    Abstract: A method for improving uniformity of an electromagnetic field inside a static microwave resonant cavity is provided. The overlap between a nodal point in one mode and an antinodal point in another node inside a microwave resonant cavity is realized by using two different types of anisotropic media, thereby improving distribution uniformity of an electromagnetic field inside a static resonant cavity. The method can reduce the complexity of cavity mechanisms of a microwave oven having a turntable and a flat panel microwave having an electromagnetic stirrer and improve static microwave treatment uniformity, thereby promoting the application of high-temperature and high-power microwave treatment in the fields such as microwave sintering, microwave smelting, and microwave chemical industry.
