Introduction. Literature review and description of the microwave imaging is presented. Underlined advantages, application, description of experimental setups, and methods for solving forward and inverse problem.Methods. Described an algorithm for solving the problem of microwave tomography using eigenfunction expansion method. Object of research is shielded (to limit the area of calculation and avoid accounting radiation waves of the continuous spectrum) transversely inhomogeneous object, with the possibility of further complications to the longitudinally inhomogeneous object. Proposed to apply eigenfunction expansion method for solving forward problem of microwave imaging.

Expected results. Improving accuracy of calculation longitudinally homogeneous object, compared with the two-dimensional problem, numerically effective calculation of the three-dimensional objects (transversely and longitudinally inhomogeneous) in comparison with other numerical methods.
