黑色半平面的衍射：物理光学方法的修正理论。

通过定义一种新的物理光学表面电流理论，计算了吸收所有入射电磁能量的黑色半平面的散射场。这种电流消除了来自反射积分的第一个驻点的反射场，而只产生了反射绕射场。入射散射场由同样的积分得到，写成了理想导电半平面。用驻相法和边缘点法计算了散射场。评估的字段是以数字方式绘制的。
The scattered fields from a black half plane which absorbs all the incoming electromagnetic energy are evaluated by defining a new modified theory of physical optics surface current. This current eliminates the reflected fields, coming from the first stationary point of the reflection integral and only creates a reflected diffracted field. The incident scattered fields are found from the same integral, written for the perfectly conducting half plane. The scattered fields are evaluated by using the stationary phase method and edge point technique. The evaluated fields are plotted numerically.
