Abstract :
A new method of determining permittivity by SVM is studied in this paper. The mapping relationship between the S parameters and the permittivity is set up by calculating a large number of S parameters from the samples with different permittivity using waveguide theory. The simulated data set is used as training data set for SVM. After being trained, the SVM is used to predict the permittivity of material from the scattering coefficients. The validity of the method is also verified using FEM.
