- The material ways are to model the honeycomb wall as an impredence surface , to express the infinite honeycomb by using periodic green ' s function , and using method of moment to establish the mathematic model , in applying the methods of moments , we choose the roof function as basic function and choose the razor function as test function ; by equating the incident field to sum of the scattering field and impledance field ; we will set up the integral equation for the surface current , solving it by mom equation . then gain it ' s reflected coefficient ' s numerical result . and we propose first the definition of the equivalent electromagnetic parameters and present a method to calculate them from the gained reflection coefficient
具体方法就是将浸渍吸收剂的蜂窝壁用表面阻抗表示，将无限大的周期结构的电场用周期格林函数来表示，选取有耗蜂窝结构中具有代表性的基本计算单元应用矩量法建立数学模型,在运用矩量法时用屋顶函数作为基函数，刀片函数作为检验函数，根据蜂窝壁表面电场必须满足入射电场等于散射电场和阻抗电场之和的规律，推导表面电场积分方程，求解蜂窝结构的表面电流，利用蜂窝的周期规律得到无限大均匀周期阵列的散射电场。
