Terahertz Plasmonics

Over the last half century, developments in optics
have fundamentally transformed the way we live. For
example, optical communications has helped bring
people across the globe closer, while consumer
electronics, in the form of CDs and DVDs, have
allowed us to store, access, and share information on
a scale that was believed unattainable several
decades ago. While innumerable technologies have been
developed across the electromagnetic spectrum, one
specific frequency band has largely been
underdeveloped. The far-infrared or terahertz (THz)
frequency range has often been referred to as the gap in the electromagnetic spectrum. This book
describes our research in exploring the physics and
applications of resonance phenomena at THz
frequencies using surface plasmon based artificial
resonant structures. Because of their unique
properties and potential device applications, these
artificial media, referred to as plasmonic
metamaterials, have attracted significant scientific
interest over the last few years. This book would
serve as an excellent reference for graduate students
and scientists working in these as well as other
areas of electrical engineering, physics and material
sciences.
