Planar antennas are switched photoconductively to generate picosecond bursts of freely-propagating radiation with usable spectral amplitudes in the 5 to 85 GHz frequency range. This radiation is used to measure the frequency-dependent, complex index of refraction of dispersive materials in reflection and transmission; new deconvolution techniques are also demonstrated for extracting frequency-domain information from time-domain measurements. Experimental results are presented for the particular case of water, and a discussion is included on the relative merits of reflection and transmission time-domain measurements on materials.
