A Position-Insensitive Measurement of the Permittivity and Permeability in Coaxial Airline

A position-insensitive measurement method of the permittivity and permeability of microwave materials in coaxial airline is described. In this method the sample position is found from the measurement data, and the errors arising from position uncertainty of the material are eliminated. Experimental results for two arbitrary locations of a ferrite sample are included to illustrate the validity of the method.
