The invention discloses a device and method for improving the uniformity of an electromagnetic field in a microwave cavity by using an adjustable artificial magnetic conductor, and the device comprises the microwave cavity and the adjustable artificial magnetic conductor, the adjustable artificial magnetic conductor is disposed in the microwave cavity, and can work in an in-phase total reflection state or an inverted total reflection state through adjustment; wherein the in-phase total reflection state means that the phase difference between the reflected wave and the incident wave of the adjustable artificial magnetic conductor is 0, and the reverse-phase total reflection state means that the phase difference between the reflected wave and the incident wave of the adjustable artificial magnetic conductor is pi. By continuously changing the two working states of the adjustable artificial magnetic conductor, the alternation of wave nodes and antinode points in the cavity is realized, so that the aim of improvi
