本文利用作者在前一篇论文中的一致近似中导出的一般解析公式来确定从电离层完全或部分反射的垂直传播HF波的波型。在反射点处也精确地计算了全三维波。在阿雷西博和特罗姆瑟的电离层修改实验的典型参数值的选择。适当地考虑了地磁场和碰撞的影响，但排除了非线性和耦合效应。结果表明，地磁场对波型的影响很大，特别是在特罗姆瑟情况下，并导致反射点以下的第一波极大值出现很大的膨胀。
General analytical formulas derived within a uniform approximation in a previous paper by the present authors are utilized for determining the wave pattern of a vertically propagating HF wave that is totally or partially reflected from the ionosphere. The full three-dimensional wave is calculated accurately, also at the reflection point. Parameter values typical of ionospheric modification experiments at Arecibo and Tromso are chosen. The influence of the geomagnetic field and collisions are properly taken into account but nonlinear and coupling effects are excluded. It is shown that the geomagnetic field affects the wave pattern strongly, especially in the Tromso case, and leads to a very high swelling in the first wave maximum below the reflection point.
