摘要

在这项工作中讨论了高频衍射的渐近方法，该方法产生关于物体延伸率的均匀近似。该方法的应用局限于旋转对称和二阶曲线近似的形状。强拉长球体的衍射更详细地加以研究。

High-frequency asymptotics for diffraction by a strongly elongated canonical object

An asymptotic approach to high-frequency diffraction which yields uniform approximations with respect to the rate of elongation of the body is discussed in this work. The method is restricted in its application to shapes that are rotationally symmetric and are well approximated by second-order curves. Diffraction by a strongly elongated spheroid is examined in more detail.
