Some special sensitive substances used for real-time detection and display of microwave field distribution in a microwave applicator cavity have been synthesized. When these substances are exposed to a strong electric field, they change color. The stronger the field, the lighter the color. The Microwave Intensity Distribution Detector (MIDD) is fabricated using these special substances. It can detect and visually display the microwave field in the cavities of various industrial microwave applicators, so that the distribution of the microwave field in the cavities can be adjusted to meet the user's requirements. The detector can be used repeatedly without limit. When the microwave is turned off, the microwave intensity distribution pattern on the detector will disappear in a few minutes, and the status of the detector will be restored as before. Compared with other methods, such as the water cup-temperature-measuring method, infrared thermal imaging method, temperature-sensitive ring method, etc., it features real-time, rapidity, intuitiveness and clear images. In this paper, several application examples of microwave intensity detector are given. They show that the MIDD is a very useful tool for both the designers and the users of the microwave cavities.
