Metasurfaces: Towards Tunable and Reconfigurable Meta-devices

Metamaterials and metasurfaces are developing exciting new frontier researches on reconfigurable materials with promising applications on tunable and active devices. The combination of metamaterials and microsystems not only uncap the controllability limits of optical metamaterials, but also pave the way for vast applications. This book focuses on structural reconfiguration of metasurfaces and metamaterials using microsystems, which have previously been developed for tiny machines and droplets formations. It covers multi-disciplinary researches on reconfigurable metamaterials and metasurfaces revealing their potential applications on densely integrated devices with working frequencies ranging from GHz to infrared region. Topics like MEMS metamaterials, frequency selective surface, photonic reconfigurable metasurfaces, and microfluidic metamaterials are just a few examples, which present lively research communities within the scope of this book. This book is intended for undergraduate and graduate students who are interested in fundamental science and technology of micro-optics and artificial materials, researchers in the field of reconfigurable and tunable metamaterials, and engineers working on tunable lens, Lidar, beam steering devices, or other applications.

Combines metamaterials, microelectromechanical, and microfluidic expertise from a multi-disciplinary standpoint Introduces a credible and efficient design method to develop metamaterials with desired controllability Provides valuable guidance for research topics on micro-system-based tunable metamaterials

Résumé
"Different types of reconfigurable metasurfaces based on MEMS, frequency selective surfaces and tunable photonic and microfluidic devices are developed throughout the entire book. These issues are covered in 10 chapters containing theory and extensive experiments. At the end of each chapter, there is a reference list for further reading. Since metasurfaces are a hot topic in microwave engineering and photonics, the book is addressed to all working in this area of research with important applications in optics and wireless communications."
