Al2O3-TiO2 and Cr2O3 Samples Refectivity in G and D bands

Data on reflectivity of samples as described in paper submitted to IEEE TST (preprint available on https:\/\/www.techrxiv.org\/\/1331106).Measured reflectivity with simple bistatic setup (two rectangular horns) at several angles of incidence, TE and TM polarization, G and W bands. Reflectivity obtained by comparison with geometrically identical fully metallic sample.
