Abstract-Applications of Optically Generated Terahertz Pulses to Time Domain Ranging and Scattering

This chapter focuses on the use of THz time-domain techniques for the measurement of time-resolved electromagnetic scattering. Electromagnetic scattering is a vast field owing to its application in a wide range of measurement techniques in addition to commercial and military radar. The vast majority of treatments look at scattering in the frequency domain. Owing to the high bandwidth, the phase coherence, and our ability to directly measure the electromagnetic field with subpicosecond resolution, optically generated THzbandwidth pulses provide a valuable new method to investigate fundamental scattering mechanisms. This introductory section provides a brief background on electromagnetic scattering, and attempts to provide a perspective on the application of THz time-domain techniques in this broad field.
