Two methods are widely used to improve absorbing properties of the microwave magnetism absorbing agent: mixing with the other material such as resistance carbon fiber absorbent, or wrapping the microwave magnetism-absorbing agent in that material. However, do these two methods coincide with each other? If not, which method should be used as better way to represent the absorbing properties of magnetism-absorbing agents? To answer these questions, both methods are carried out on the same magnetism absorbing agents, of which the results are compared. Distinct difference between these measured results is found, and the possible reasons for the difference are also discussed.

The sol-gel method is used to fabricate Fe crystalline powders coated with SiO 2 . By controlling the molar ratio R of diluted water to tetraethoxysilane (TEOS), Fe powders coated with SiO 2 with different morphological characteristics are fabricated. The influence of the core diameter on electromagnetic parameters is investigated. The effect of the amount of the coating material SiO 2 on electromagnetic parameters is given. Radar wave absorbing properties of Fe coated with SiO 2 and TiO 2 respectively are compared.

The method extracting the electromagnetic parameters from scattering coefficients was studied in this paper. The Support Vector Machine (SVM) method is used to solve the inverse problem of parameters extraction. The mapping relationship is set up by calculating a large number of S parameters from the samples with different permittivity by using transmission line theory. The simulated data set is used as training data set for SVM. After the training, the SVM is used to predict the permittivity of material from the scattering coefficients.
