ResumoPublisher SummaryThis chapter discusses the one particular type of resonator—the microwave resonant structure. With the application of superconductivity, these devices have recently been developed to an extremely high order of perfection so high that they are used in some applications where entirely different types of resonators have traditionally been used. The chapter discusses the response of a superconducting surface to microwave frequency electromagnetic fields up to the dc critical field in magnitude. Experimental results are given and the parts of the theory of superconductivity that relate directly to understanding the performance of superconducting resonators are briefly outlined. The practical techniques for designing and building high-Q superconducting resonators and for measuring their properties are discussed. Suitable materials and methods for preparing high-quality surfaces are discussed. Ways of coupling to high-Q resonators and circuits to measure the Q and resonant frequency are also described. The chapter reviews the number of applications in several areas of experimental physics and technology where superconducting resonators have already enabled significant advances to be made. In order to be useful to the widest audience, the focus of this chapter is primarily on small-scale laboratory applications rather than large-scale applications such as accelerators.
