摘要：We have developed rotationally symmetrical coaxial chambers for measurementsof dielectric parameters of disk-shaped samples, in the frequency range from 1 MHz toseveral hundred MHz. The reflection coefficient of the chamber is measured and thedielectric parameters are hence extracted utilizing a high-accuracy quasistatic numericalmodel of the chamber and the sample. We present this model, which is based on the methodof-moments solution of a set of integral equations for composite metallic and dielectricbodies. The equations are tailored to bodies of revolution. The model is efficient andaccurate so that the major contribution of the measurement uncertainty comes from themeasurement hardware.
