Reflectometry Measurements of the Loss Tangent in Silicon at Millimeter Wavelengths
Grace E. Chesmore, Tony Mroczkowski, Jeff McMahon +3
We report here on measurements of the reflectivity and loss tangent measured in the W-band (80-125 GHz) and D-band (125-180 GHz) in two samples of float zone silicon with intrinsic…
