Abstract: A microwave heating method and a microwave heating device are provided. The microwave heating method includes the following steps. An electric field mode distribution at each frequency point generated by the microwave outputted from each input port of the heating chamber is calculated. A frequency, phase, and power of the microwave outputted from each input port are changed to generate a corresponding electric field mode distribution. The electric field mode distributions generated by the input ports are synthesized into a synthesized electric field mode distribution. A power density distribution is calculated. It is calculated whether spatial uniformity of the power density distribution is greater than a target value. The controller heats the object to be heated through the microwave corresponding to the frequency, phase, and power emitted by the microwave transmitter corresponding to each input port.
