FIELD: physics.
SUBSTANCE: first antenna receives an electromagnetic field near the inspected object, a second antenna additionally receives a background electromagnetic field from the inspected object, the electromagnetic field received near the inspected object and the background electromagnetic field received far from it undergo spectral analysis, the obtained spectral characteristics are compared and the internal state of the material of the inspected object is determined from their difference.
EFFECT: enabling inspection of the internal state of material located in the region of an electromagnetic wave generated by a radiating antenna.
