Analysis of the Mathematical Model of Open Coaxial Measuring Microwave Converters

摘要

The open coaxial sensor (OCS) enables online non-destructive testing of a wide range of objects. To solve the electrodynamics problem in the OCS design, this paper puts forward a mathematical model for an OCS with a sample located outside the sensor, and performs the theoretical calibration of the OCS in cylindrical form. The proposed method can be applied to OCSs with different forms of working area. The findings help to develop algorithms and programs for qualitative analysis on OCS features, and to compute the parameters and functions of OCS design. In addition, the analysis method can identify the basic and side effects of the qualitative level, and facilitate the construction of actual OCS designs.
