Terahertz (THz) radiation is electromagnetic radiation whose frequency lies between the microwave and infrared regions of the spectrum. We cannot see THz radiation, but we can feel its warmth as it shares its spectrum with far-infrared radiation. Naturally occurring THz radiation ﬁlls up the space of our everyday life, yet this part of the electromagnetic spectrum remains the least explored region mainly due to the technical diﬃculties involved in making eﬃcient and compact THz sources and detectors. The lack of suitable technologies led to the THz band being called the “THz gap”. This technological gap has been rapidly diminishing for the last two decades. Optical technologies have made tremendous advances from the high frequency side, while microwave technologies encroach up from the low frequency side. This chapter gives a brief perspective on the basic properties of THz radiation and its interaction with materials, which lays down the foundation to discuss the progress of THz science and technology in subsequent chapters.
