Abstract

With the advent of reliable sources of ultrashort optical pulses, photoconductive switches and photoconductive sampling have become usual methods that allow to generate and to detect ultra-fast electric pulses. Recent experiments have shown that commuting devices of optoelectronic pulses associated with appropriate antennas can be used to generate, control and detect picosecond bursts of electromagnetic radiation. It leads to various applications1 such as the transient radiation properties of antennas2, the scattering of radiation by three-dimensional objects3 or the characterization of material by the coherent microwave transient spectroscopy technique4.
