MILLIMETER WAVE RESEARCH
Abstract
Analyses are being carried out to determine the characteristics and usefulness of a variety of transmission methods and associated components for possible utilization in the 1 millimeter to 0.1 millimeter wavelength region of the electromagnetic spectrum. Preliminary work is underway on equipment and instrumentation to be used in making measurements above 300 Gc. The report describes and compares the characteristics of enclosed waveguides, the H-guide and trough guide, single-wire transmission lines, dielectric waveguides (and fiber optics), the beam waveguide, and refractive or reflective transmission methods employing repeated image formation. A further study was made on Fresnel zone plates, and a description is given of their behavior over a wide frequency range, showing how they may be used as focusing devices or as filter elements.
