Abstract :
In this paper, millimeter wave free-space quasi-optical spectroscopy technique is applied to determine the transmittance, complex refractive index and complex dielectric permittivity over 30 GHz to 120 GHz range. The imaging procedure is based on using these data for a solvable inverse imaging reconstructing problem. An image reconstruction is achieved to give the high resolution reconstructed images of the sample over a wide frequency range.
