Abstract
A near-field probe is applied to perform microwave polarimetric measurements with a subwavelength spatial resolution. The probe is a symmetrical cross-slit antenna formed by two very thin orthogonal slits at the end of a circular waveguide. The mapping is phase-sensitive and can be done with a subwavelength spatial resolution of at least λ/16 in conductors. The probe may also be used for local measurement of Hall mobility in semiconductors.
