提出了一种定量评价电磁阻抗匹配度的δ函数法。利用测量的α-Fe/Fe 3B/Y2 O3纳米复合材料的电磁参数计算了匹配度。与反射损耗和四分之一波长原理理论相比，该方法准确地揭示了微波传输和反射特性的内在机理。一种可能的蜂窝结构，有前途的高性能的微波吸收，根据该方法设计，也提出了。
A delta-function method is proposed to quantitatively evaluate the electromagnetic impedance matching degree. Measured electromagnetic parameters of alpha-Fe/Fe3B/Y2O3 nanocomposites are applied to calculate the matching degree by the method. Compared with reflection loss and quarter-wave principle theory, the method accurately reveals the intrinsic mechanism of microwave transmission and reflection properties. A possible honeycomb structure with promising high-performance microwave absorption, devised according to the method, is also proposed.
