摘要
作者根据由强扰动理论推出的颗粒混合媒质等效介电常数和等效导磁率的计算公式,讨论了吸收剂粒子外形对吸波材料电磁特性的影响.从理论上导出了吸收剂粒子的最佳外形.讨论了多外形铁氧体吸波材料等效介电常数和等效导磁率的计算.实验结果表明,这些理论预测公式具有较高的准确性.
Based on the formulas of effective permittivity and permeability of granular media derived from the strong fluctuation theory, the influence of the shapes of wave-absorbing particles was discussed. From the theory, the optimum shape of wave-absorbing particles was recommended and the prediction formulas of permittivity and permeability for ferrite wave-absorbing materials were given. It has been found that the experimental results are in good agreement with theoretic. The work would be helpful to the design of antiradar coating materials.
