Query: Identification of object composition with Magnetic Inductive Tomography   The inductive response of an object to an oscillating magnetic field reveals
information about its electrical conductivity and magnetic permeability. Here
we introduce a technique that uses measurements of the angular, frequency and
spatial dependence of the inductive signal to determine object composition.
Identification is performed by referencing an object's inductive response to
that of materials with mutually exclusive properties such as copper (high
electric conductivity, negligible magnetic permeability) and ferrite
(negligible electric conductivity, high magnetic permeability). The technique
uses a sensor with anisotropic sensitivity to discriminate between the
different characters of the eddy current and magnetisation driven object
responses. Experimental validation of the method is performed through Magnetic
Induction Tomography measurement with a radio-frequency atomic magnetometer.
Possible applications of the technique in security screening devices are
discussed.
