Abstract
The generation of free-space ultrawideband (UWB) short-pulse (SP) electromagnetic radiation by laser pulses has been investigated vigorously in the past few years 1–8. A variety of applications have been developed out of this innovative technique in the terahertz regime, such as, spectroscopic characterization of materials in the far-infrared region 9, transient nonlinear properties of dielectric materials at the submillimeter wavelengths 10, novel methods for characterizing semiconductor surfaces and interfaces 4, and very recently, terahertz time-domain imaging due to highly frequency-dependent absorption and dispersion for most chemicals 11. When the photoconducting antennas are used in impulse radar communication and IFF system, the gigahertz (GHz) range is more applicable than the terahertz (THz), as electronic instrumentation is more mature.
