Short-pulse scattering measurements from dielectric spheres using photoconductively switched antennas


Journal Article

Planar antennas are switched photoconductively using optical pulses generated by a picosecond laser system. The freely propagating radiation, of picosecond duration and with bandwidth extending from 5 to 75 GHz, is used to perform short-pulse scattering measurements on three-dimensional targets. Results are shown for scattering from dielectric spheres, with the time-domain results clearly showing the early and late-time scattered signal. All measurements are compared with theory, directly in the time domain.
