Abstract

Abstract

This paper presents the experimental results of a 95 GHz quasi-optical mode converter. The test system is a near-field scanning system based on millimeter wave antenna. The mode converter includes a Vlasov launcher, a quasi-elliptical mirror and two phase correcting mirrors. It converts the TE62 mode in a circular waveguide of 5.62 mm radiusinto a Gaussian mode of 22.4 mm waist. The scalar correlation coefficient is 97.43%, and the vector correlation coefficient is 88.65%.
