摘要
Abstract
In order to improve absorbing properties of material effectively, this paper researched absorption properties of ferrite mixed with semiconductor particles. Using effective electromagnetic parameter model, it figured out the cubage and conductivity of semiconductor particles which did not destroy resistance matching characteristic. Through calculating the reflection, resistance matching characteristic and attenuation coefficient of the material, it is proved that magnetism-absorbing agents mixed with semiconductor particles could reduce real complex permittivity and increase imaginary. It is able to enhance the ability of attenuating electromagnetic wave, improve absorbing properties, and meanwhile keep the resistance matching with air.关键词
