Resonance: Long-Lived Waves, a new volume in the Interface Transmission Tutorial Book series, introduces long-life resonance properties for telecommunications. The book's authors review the general analysis methods of interface transmission, giving many examples and applying these methods to telecommunications systems (materials and devices). Each chapter introduces and defines the long-lived resonances, their path states and phase shifts, and applications.

This book is suitable for materials scientists and engineers in academia and R&D, and may also be appropriate for applied physicists.
