Abstract: A method for reconstructing a dielectric image using electromagnetic waves, comprising: acquiring a measurement value of the electromagnetic waves; generating a matching system matrixes between the meshes; generating a smoothed dyadic Green's function matrix; generating an electromagnetic wave calculation value; calculating a misfit error between the acquired electromagnetic wave measurement value and the generated electromagnetic wave calculation value, and checking whether a change of the calculated misfit error satisfies a predetermined optimization determination condition; updating dielectric parameters at the meshes; and outputting a reconstructed dielectric image in the image reconstruction region.

Abstract: An apparatus and method of controlling a temperature of a matching material used in an apparatus for generating a tomographic image is disclosed. The method includes measuring a temperature of a matching material in which an object is immersed in an apparatus for measuring a shape of an object, setting a set temperature at which an amplitude and a phase of an electromagnetic wave that passes through the matching material are maintained, based on the measured temperature of the matching material, and controlling the temperature of the matching material to be higher than the set temperature.
