Extension of the ``Thin-Sample Method'' for the Measurement of Initial Complex Permeability and Permittivity

Abstract

A summary is given of the theory of measurement of complex relative permeability and permittivity of low conductivity materials by the thin-sample method using a slotted transmission line. The equations from which to calculate the electrical properties from the measured parameters are extended to apply to a commercial slotted line and thus to a more complex system than that used by other workers. Some errors of the measurements are discussed and various correctional equations derived by other workers are given.
