对碳纤维复合材料吸波材料进行了优化设计。预测结果基于介电常数模，其服从混合物的对数定律，而介电损耗角正切则通过混合物的线性定律相关。对数据点进行的线性回归分析提供了用于预测不同频率下的有效折射率的常数。编写了一个优化程序来计算每层所需的碳纤维浆料的最佳量和厚度。计算结果与实测数据吻合较好。
Optimization of the carbon fiber composite for a microwave absorber is presented. The predicted results are based on the modulus of permittivity which obeys a logarithmic law of mixtures while the dielectric loss tangents are related through a linear law of mixtures. Linear regression analysis performed on the data points provides the constants which are used to predict the effective permittivities at different frequencies. An optimization program is written to compute the optimum amount of carbon fiber paste and thickness required for each layer. As shown, the predicted results agree quite well with the measured data.
