Broadband dielectric measurements with picosecond transient radiation

View publication


Picosecond transient radiation from optoelectronically pulsed integrated antennas is used for coherent microwave spectroscopy in the 10 to 125 GI Iz frequency range. The experimental apparatus is characterized using samples with predictable loss and dispersion properties. We present measurements of the frequency dependent absorption coefficient and refractive index of materials performed using this set-up. © 1988 SPIE.
