A six-port technique application of measuring complex permittivity and permeability

A six-port technique is presented for simultaneous measurement of complex permittivity and permeability of a given material. A dual six-port network analyzer is employed to measure the scattering parameters. The complex permittivity and permeability are computed from the scattering parameters of a transmission line filled with the material to be tested. Measured ϵr, μr, data for Teflon agree well with known values. The identical samples are measured with a six-port ANA and an automatic network analyzer, HP8510B. The measured data of the six-port ANA and the HP8510B agree well with each other by comparison.
