Dielectric resonators are devices used in microwave and radio frequency applications to store and manipulate electrical energy. They are typically made of ceramic or crystalline materials with high permittivity, allowing them to store a large amount of energy in a small volume. Dielectric resonators are commonly used in filters, oscillators, and antennas to enhance performance and efficiency. Research in the area of dielectric resonators involves studying the design, fabrication, and optimization of these devices for specific applications. This includes exploring new materials with improved properties, finding novel geometries for better performance, and investigating the electromagnetic behavior of dielectric resonators in different environments. Overall, research in this area aims to improve the efficiency and effectiveness of microwave and RF devices by utilizing dielectric resonators.
