Passive Microwave Sensors Based on Quasi-BIC

With the rapid development of automated systems, it became necessary to use wireless communication systems to monitor a variety of different parameters. Wireless sensors are actively used in many modern intelligent systems to track and control various characteristics of the system and its environment. The task of developing compact sensors with high sensitivity and measurement accuracy is extremely urgent in this field. In this paper, two microwave sensor designs based on dielectric resonators, whose parameters are optimized for quasi-BIC mode maintenance, have been proposed. Furthermore, the application of these sensors extends to the realm of temperature tracking, water temperature control, and impurity detection, showcasing their potential in manufacturing processes, wireless power transfer, and various other industrial applications.
