This book provides a thorough overview of methods and approaches to the experimental characterization of superconductors at microwave frequencies, and includes a detailed description of the two main techniques, both based on the use of coplanar waveguide resonators, that the authors employed to investigate the properties of unconventional superconductors. In the second part several case studies are described, covering a large spectrum of materials and issues. Particular emphasis is given to recent hot topics concerning iron-based superconductors, both of fundamental nature and relevant for applications. The book is intended as a learning tool for researchers in the field, and serves as a guide providing inspiring examples of the use of coplanar resonator techniques to address key topics in the field of unconventional superconductivity.
