Modeling and Computing Example for Effective Electromagnetic Parameters of Multiphase Composite Media

摘要

A method using strong fluctuation theory (SFT) to compute the effective electromagnetic parameters of multiphase composite media, and common materials used to design radar-absorbing materials, is demonstrated. The effective electromagnetic parameters of ultrafine caxbonyl-iron (DT-50) and fiber fabric, which are both multiphase composite media and represent coated and structured radar absorbing materials, respectively, are investigated, and the corresponding equations of electromagnetic parameters by using the SFT axe attained. Moreover, we design a program to simplify the solutions, and the results are discussed.
