Abstract
An open resonator formed by a flat and a spherical reflector, which with suitable scaling would be appropriate for operation at near-millimeter wavelengths, has been constructed and tested. For ease of fabrication and study, we have performed preliminary experiments in the microwave range of 8.0 to 12.5 GHz on a prototype resonator, but scaling to higher frequencies is quite straightforward. Partial reflectors were constructed of metal strip gratings which have an inductive amplitude reflection coefficient of magnitude about 0.985 at 10.0 GHz. By tuning the frequency of the incident plane-polarized radiation, the Gaussian TEMcimn cavity resonances have been observed in both transmission and reflection. The center frequencies and line widths of several of these resonances have been measured. A confocal resonator of this type would be appropriate as a scanning interferometer for high-resolution spectral analysis of the radiation of a millimeter wave source, and resonators with curved metal grid reflectors could be used for millimeter wave laser oscillators.
