| 摘 要： | 本文根据强扰动理论,导出了随机取向颗粒混合媒质等效电磁参数的计算方法。将这一理论应用于吸波材料的研究,找出了吸收剂粒子的最佳外形;获得了多粒子外形铁氧体吸波材料等效介电常数和等效磁导率的计算公式。测试数据表明,理论计算与实际测量值吻合得很好。

| Abstract: | Based on the strong fluctuation theory, the calculating method for effective electromagnetic parameters of srochastically oriented granular media is derived. Applying the theory to study absorbed materials, the optimum shape of absorbed particles in antiradar coat-multiple shape ferrite absorbed materials is ober effective permittivity and permeability of multiple shape ferrite absorbed materials is obtained. The measured results are in good agree-ment with the calculating ones. |
