| Abstract: | This paper details the principle of measurement of complex permittivity and permibilityusing free-space method ,and discuess some basic problems of the construction of the system and thecalibration tichniqu.The measurement sensitivity of this method also modeled by computer.This methodcan be expanded to broad-band meaeasurement of dlelectric materials,and accuracy results can be obtainedafter calibration,but numerical simulation shows the this method can not be used to the case of low-lossymaterials. |
