Studies of Millimeter-Wave Diffraction Devices and Materials. Phase III.
Abstract
This study is a continuation of earlier work wherein Battelle examined a variety of diffraction electronics effects. The concept involved is one where a dielectric waveguide interacts with a nearby periodic structure or grating through evanescent mode coupling. By changing the period of the nearby structure, a beam steerable antenna is achieved. The earlier work revealed mechanical, fluidic, and laser-photoconductor ways of achieving a grating containing alternating regions of high- and low- electrical conductively. The center frequency for the past and current work was 94 GHz. This region of the spectrum was selected because discrete phase shifter technology is not sufficiently advanced to permit conventional phased array assembly at this frequency. The diffraction electronics concept offered the potential by-pass of the need for phase shifters, and hence it was necessary to explore the concept for ways to achieve rapid beam steering.
