This comprehensive book delves into diverse methods and approaches for characterizing superconductors at microwave frequencies, offering a detailed account of the two primary techniques employed by the authors. These techniques, both based on the utilization of coplanar waveguide resonators, played a pivotal role in investigating the unique properties of unconventional superconductors. In the second part, the book presents several case studies, encompassing a wide range of materials and topics. Special attention is given to recent hot topics related to iron-based superconductors, encompassing both fundamental aspects and their significant implications for practical applications. Designed as a valuable learning resource for researchers in the field, this book serves as a guide, showcasing inspiring examples of how coplanar resonator techniques have been instrumental in addressing key issues in the realm of unconventional superconductivity.

Introduction:
The study of superconductivity, the phenomenon in which certain materials exhibit zero electrical resistance at extremely low temperatures, has garnered significant attention in recent years. Superconductors have the potential to revolutionize various fields, including energy storage, transportation, and electronics. However, the characterization of superconductors at microwave frequencies remains a challenging task due to their complex behavior and the limitations of traditional measurement techniques.
Methods and Approaches:
This book provides a thorough overview of methods and approaches to the experimental characterization of superconductors at microwave frequencies. It begins by discussing the theoretical background and principles of superconductivity, followed by an introduction to the coplanar waveguide resonator technique, which is a powerful tool for studying superconductors at microwave frequencies. The authors then discuss the two main techniques they employed to investigate the properties of unconventional superconductors: time-domain reflectometry (TDR) and microwave surface resistance (MSR).
Time-Domain Reflectometry (TDR):
TDR is a technique that measures the reflection of microwave signals from the surface of a superconductor. It provides information about the density of states, the energy gap, and the phase shift of the superconducting material. The authors describe in detail how TDR is used to study the properties of unconventional superconductors, including cuprate superconductors, iron-based superconductors, and high-temperature superconductors.
Microwave Surface Resistance (MSR):
MSR is a technique that measures the resistance of the surface of a superconductor to microwave excitation. It provides information about the surface state density, the density of impurities, and the electronic structure of the superconducting material. The authors discuss how MSR is used to study the properties of unconventional superconductors, including cuprate superconductors, iron-based superconductors, and high-temperature superconductors.
Case Studies:
In the second part of the book, 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 case studies provide insights into the behavior of iron-based superconductors under different conditions, such as high magnetic fields, high temperatures, and external perturbations.
Conclusion:
This book is intended as a learning tool for researchers in the field, and serves as a guide to providing inspiring examples of the use of coplanar resonator techniques to address key topics in the field of unconventional superconductivity. The authors have done a remarkable job in presenting the complex subject matter in a clear and concise manner, making it accessible to a wide range of readers. The book is a valuable resource for anyone interested in exploring the experimental characterization of superconductors at microwave frequencies, and serves as a guide providing valuable insights into the latest developments in the field.
