Techniques for design of filters, ferrite devices, diode mounts, and radiation detectors in oversize waveguide are being investigated. Theoretical and experimental results are presented in this report. The 2 and 0.9 mm regions of the dielectric slab filters were evaluated. In addition, the effect of small-waveguide dissipation on the dielectric slab filters was derived. Experiments have continued on Faraday rotation in oversize waveguide. First measurements have been made at 1 mm. An isolator has been constructed. A new type of millimetersubmillimeter mixer using bulk semiconductor was analyzed and successfully demonstrated. The analysis was checked using a low-frequency-prototype consisting of a bolometric mixer operating at 1 Mc. Millimeter mixing was obtained in the 30 to 40 Gc region using bulk n-type indium antimonide as the mixer element. A conversion loss of 24.5 db was measured using nonoptimum material. When corrected for mismatch losses and other effects, a conversion loss of 15.5 db is calculated. Author
