Data-reduction Method for Simultaneous Measurement of Permittivity and Permeability with a Short-circuited Transmission Line
Based on nonlinear least-squares optimization techniques and interpolation techniques,a datareduction method for determining the complex electromagnetic parameters of materials with a shortcircuited transmission line is presented in this paper,which takes frequency as an independent variable in order to establish independent reflection equations for the determination. After only one frequency-sweeping measurement,reflection equations are constructed by interpolation techniques and solved by nonlinear least-squares optimization techniques. With the help of this method,the shortcircuited transmission line method can simultaneously measure the complex permittivity and permeability on a single sample at a single position in the shorted line. The optimization procedure is enough robust to converge to the correct value because of its less dependence on an initial guess.
