Here the loss of both a dielectric sample and a shielding conductor is taken into account. A term with 1/r among the components of the finite element matrix is analytically integrated over a triangular ring quadratic element. Also, the inverse problem, that is, the estimation of the complex permittivity of a dielectric from a resonant frequency and an unloaded quality factor, is formulated and its usefulness is confirmed through some computed results for dielectric plates and deformed lossy sheets.}, pages = {10--19}, title = {Finite Element Analysis for Complex Permittivity Measurement of a Dielectric Plate and Its Application to Inverse Problem}, volume = {84}, year = {} }
