Research on the influence of electrode position on the sensitivity field based on Ansoft Maxwell

In this paper, Ansoft Maxwell software was used to build the model, and sensitivity field analysis and reconstruction imaging were carried out with Matlab. Firstly, Ansoft Maxwell finite element analysis software was used to simulate the sensor model, and different capacitance values were obtained by exciting different electrode plates in the sensor. Secondly, the imaging of the sensitivity field is realized based on Matlab software, and the influence of different electrode plates on the sensitivity field is analyzed. Finally, 2d ECT image reconstruction of the cylinder model is carried out, and good results are obtained.
