PROJECT TITLE :
New Uncertainty Analysis for Permittivity Measurements Using the Transmission/Reflection Method
We tend to have developed a brand new algorithm for the uncertainty analysis of permittivity calculations of high-loss materials using the transmission/reflection (T/R) method. Within the T/R methodology, many calculation procedures are performed to derive the permittivity. In our technique, the permittivity springs from measured -parameters by solving an equation in which -parameters are included in the form , where is a weighted issue to be optimized to attenuate the uncertainty. We confirmed its efficacy by doing numerical calculations, in addition to using actual measurement data for many materials obtained with a waveguide fixture. We tend to also thought-about the result of the kind of calibration technique used on a vector network analyzer on the permittivity uncertainty, and quantitatively clarified that it is essential to develop a highly correct -parameter measurement system to perform permittivity measurements using the T/R technique accurately.
