摘要
从电磁参数出发研究了DT 50 环氧复合材料体系的电磁波反射行为。考虑吸收剂粒径、电导率、趋肤效应等因素,将A(a,σ,εi,ω)引入经典Maxwell Garnett公式。Maxwell Garnett公式及其扩展公式均适用于一般金属颗粒均匀复合体系的等效电磁参数预测,扩展公式比经典公式更准确些。
The electromagnetic parameters of DT-50/exopy composite system are discussed. Considering the effect of radius, conductance and penetration of ultra-fine absorbent, extended Maxwell-Garnett theory to which the function A(a,σ,εi,ω) is introduced can simulate the electromagnetic properties of the composite system. Maxwell-Garnett formula and extended M-G applies to most composite systems embedded in metal particles but can't calculate the effective EM parameters of uneven system. Extended M-G formula is more accurate.
