摘要

Electromagnetic tomography (EMT) is of potentially practical value in the field of both industrial and biomedical detection. However, the sensitivity of the sensor array on the changes of the object field distribution, sensitivity and accuracy of the system, measurement precision and system stability are highly dependent on excitation condition. In this paper, the excitation condition of EMT is analyzed with COMSOL Multiphysics the finite element analysis software, the effect can be discussed in two aspects. One is the direct effect on the measurement results from the change of the excitation condition; another is the changing affect on the distribution of integrated sensing field. In this paper, two elements were set which would lead to the change of the excitation condition, the excitation frequency and the excitation strategy. These two elements would affect the sensing field from diverse aspects.
