Summary

The adaption of plasmonic concepts from the optical region of the spectrum to the terahertz (THz) band offers the exciting potential to realize new applications as well as overcome some of the limitations of the band. This chapter examines some of the sensing applications of THz radiation that make the band so interesting. It shows how THz plasmonics can be realized by way of semiconductor and engineered metal surfaces and how they can be applied toward sensing. Next, the chapter discusses the theory and properties of surface plasmon polaritons (SPPs) and spoof SPPs (SSPPs) as well as their sensing applications. It also describes the use of THz plasmonic antennas for receiving and concentrating THz radiation and the phenomena of extraordinary transmission (ET) in the THz band. The chapter concludes with a description of some of the possibilities offered by the exciting new material graphene.
