Abstract
Planar antennas are switched photoconductively to generate picosecond bursts of freely-propagating radiation with usable spectral amplitudes from 5 to 85 GHz. This radiation is used to perform reflection and tr ansmission measurements on materials, with experimental results presen ted for the complex index of refraction of water. We compare the relat ive merits of time-domain reflection and transmission material measure ments and present new deconvolution techniques for extracting frequenc y-domain information from time-domain measurements.
