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(More)
This paper presents a high-resolution high-power free-space dielectric and magnetic measurement technique for evaluating the complex dielectric permittivity and complex magnetic permeability of solid materials in millimeter waves at room temperature. This method enables us to obtain broad-band highresolution transmittance spectra using a quasi-optical(More)
Transmittance measurements on various single crystal ferroelectric and dielectric materials, BaTiO(3), SrTiO(3), LiNbO(3), LiTaO(3), (PbMg(1/3)Nb(2/3)O(3))0.73-(PbTiO(3))0.27, LaAlO(3), and Bi(4)Ge(3)O(12), over a broad millimeter-wave (MMW) frequency range have been performed. Frequency dependence of the complex dielectric permittivity has been measured in(More)
