where for simplicity the frequency terms are omitted, where Ei=(x,y,z) and Ej=(x,y,z) are 3D electromagnetic fields (x,y,z) distribution from electromagnetic sources located at the positions of physical sources (from 1 to N) in the electromagnetic tomography system and at the position of the physical receivers (from 1 to M) correspondingly, taken as conjugate values, and wherein Object Factori,j is the “ij”th component of the object factor, from transmitter i to receiver j.
