Abstract

The electromagnetic responses of metal objects can be determined by their electromagnetic polarizability tensors. In landmine detection and geophysics, the electromagnetic tensors of metal objects are usually determined from multi-position measurements or simulations. In this paper, the electromagnetic tensors of metal objects are obtained from rotation measurements. This rotation measurement method can be applied to magnetic sensors with magnetic fields from one direction, e.g. in-line metal detectors.
