Abstract
The construction and performance measurement of a quasi-optical Fresnel rhomb for millimetre wavelengths is described. The Fresnel rhomb was found to operate successfully over W-band with an efficiency ranging from 85 to 95% as the frequency increased from 85 to 99 GHz. Thus, the device offers a wideband performance quarter-wave plate, suitable for quasi-optical systems at millimetre wavelengths.
