Kemper Hall, Room 3182

 

 

The Microwave/Millimeter Wave Laboratory is employed for both teaching and research activities. On the teaching side, students learn passive and active RF and microwave device analysis, and the design, fabrication, and testing of RF and microwave filters and circuits. In the course of their studies, the students also learn how to operate state-of-the-art microwave equipment (see Fig. 1) courtesy of generous donations from Agilent Technologies (formerly a division of Hewlett Packard). A camera and darkroom in the laboratory permits the rapid fabrication and evaluation of planar microwave circuits. A compact computerized, anechoic chamber (see Fig. 2) is available for both teaching and research use for antenna pattern testing at microwave (≤ 40 GHz) and millimeter-wave frequencies (40-220 GHz and above). The primary plasma diagnostics research in this facility has been directed toward imaging array development, quasi-optical beam splitter and notch filter arrays, and the use of phased antenna arrays for beam steering and beam focusing/defocusing applications for imaging reflectometry.
