摘要：
The influence of interface effect between inclusion particles and matrix in composite on electromagnetic wave absorbing characteristics has been investigated. Firstly, an effective permittivity model of composite with interfacial shell is established. And then the formula for the effective permittivity and permeability of composite with interface is derived based on the effective medium theory. According to the proposed formula and transmission line theory, the influence of the interface effect on the electromagnetic wave absorption characteristics is discussed. The size effect of the inclusion on the reflection loss of absorbing composite is also studied. All these results indicate that the interface effect of inclusion particle should be considered in design and application of the electromagnetic wave absorbing composites when the size of the filler particles is in micron range.
