Energy conservation of the scattering from one-dimensional strongly rough dielectric surfaces is investigated using the Kirchhoff approximation with single reflection and by taking the shadowing phenomenon into account, both in reflection and transmission. In addition, because no shadowing function in transmission exists in the literature, this function is presented here in detail. The model is reduced to the high-frequency limit (or geometric optics). The energy conservation criterion is investigated versus the incidence angle, the permittivity of the lower medium, and the surface rms slope.
利用单反射的基尔霍夫近似并考虑阴影效应，对一维强粗糙介质表面散射的能量守恒进行了研究，包括反射和透射情况。此外，由于文献中不存在透射情况下的阴影函数，本文详细给出了该函数。该模型简化为高频极限（或几何光学）。研究了能量守恒准则与入射角、下层介质的介电常数以及表面均方根斜率的关系。
