Abstract: The present application belongs to the technical field of monitoring of durability of concrete, and particularly relates to a method for optimizing a structure of an electrical capacitance tomography sensor and analyzing an electromagnetic field. A specific process of the method includes eight steps: parameter setting, geometric setting, material setting, mesh generation, physical field setting, solution, sensor structure optimization and calculation of electromagnetic field distribution. The method proposes a new concept for solving a forward problem of an ECT system based on COMSOL software. After modeling is completed, uniformity of a sensitive field of the ECT sensor is analyzed according to calculation results, and structural parameter values of components of the ECT sensor are adjusted to seek an optimal design scheme.
