提出一个数值方法,计算当平面波垂直于蜂窝板入射时浸渍吸收剂的蜂窝的反射系数。在引入蜂窝壁表面阻抗后,借助于周期格林函数对无限大蜂窝表面建立了电场积分方程,用矩量法求解未知的表面电流。在8~12 GHz频段内,得到的不同蜂窝高度、不同吸收剂和不同浸渍厚度的数值结果表明,所提出的方法是高效的,可用于蜂窝制备和吸波结构的工作中。 A numerical method is proposed to calculate the reflection coefficient of the honeycomb impregnated with absorbent when the plane wave is perpendicular to the incidence of the honeycomb panel. After the surface impedance of honeycomb was introduced, the integral equation of electric field was established for infinite honeycomb by means of periodic Green’s function, and the unknown surface current was solved by moment method. Numerical results of different honeycomb heights, different absorbers and different impregnation thicknesses in the 8-12 GHz band show that the proposed method is efficient and can be used in the work of honeycomb preparation and wave absorbing structures.
