Abstract

The present disclosure relates to an asymmetric compensation method and apparatus for a two-port near field probe, a device, and a storage medium. The method includes: obtaining a first scattering parameter collected by a symmetric two-port network established based on a symmetric two-port near field probe; obtaining a second scattering parameter collected by an asymmetric two-port network established based on an asymmetric element; obtaining an overall response of a calibration network in a magnetic field environment, the calibration network being established based on the symmetric two-port near field probe and the asymmetric element; calculating a calibration factor based on the scattering parameter of the symmetric two-port near field probe, the scattering parameter of the asymmetric element, and the overall response of the calibration network in the magnetic field environment; and compensating the symmetric two-port near field probe according to a calibration factor.
