Millimeter-Wave Exposure System Augmentation
Abstract
Dielectric lenses, a pedestal, and a remote-controlled positioner were designed, constructed, delivered, and installed for the Armstrong Laboratory/OEDR millimeter-wave facility which consists of a 75-W 35-GHz transmitter, a 50-W 94.5-GHz transmitter and a millimeter-wave anechoic chamber. Gaussian optics was used in the lens design and concentric sets of grooves were used to optimize the transmission characteristic of the lenses by impedance matching. With the lenses, power densities on the order of 1 W/sq. cm. can be produced for a spot with a 3-cm (1.18 in.) diameter. A pedestal system was designed and constructed which could support specimens and be millimeter-wave transparent. The remote-controlled positioner is capable of positioning a millimeter-wave field probe within a 1 m X 0.5 m X 0.5 m (3.28 ft X 1.69 ft X 1. 69 ft) volume. The system is also capable of feeding back to a remote computer the position of the probe.
