Abstract

Historically, the Thru-Reflect-Line (TRL) method for complex permittivity and permeability extraction has been sufficient in producing accurate and cost-effective measurements of material characteristics. However, this method requires rigorous setup for accuracy and more time to collect all necessary data samples. The Position-Insensitive and Calibration-Independent (PiCi) method for complex permittivity extraction offers an alternative method that is quicker and simpler, requiring less time and only two measurements - sample and line - instead of the TRL method's four - thru, line, reflect, and sample. This method is currently limited to coaxial line and rectangular waveguides only. This paper extends the PiCi method to stripline using unique functions in the Newton-Raphson root search algorithm different from the functions used to characterize the waveguide and coaxial line parameters. The results show the stripline provides an accurate estimation of the material's permittivity and permeability without adjusting for detector mismatch within the network analyzer. Further, detector mismatch correction provides improved stability at all frequencies of observation and increased precision at a sufficiently high frequency. Thus, this research validates another comparable method to the PiCi method for material characteristic extraction for the waveguide and coaxial line, further reducing measurement time and improving cost effectiveness.
