在Chou的著作（IEEE Trans.Propag.，第60卷，第1期，第340-350，2012年1月），其被扩展为通过将一般双曲曲面表示为具有延续到复空间中的曲面曲率的椭圆曲面来处理一般双曲曲面。该解决方案允许一个模型更现实的散射体与本地化的凸和凹的表面，根据一致的几何衍射理论（UTD）型散射反射和边缘衍射机制的基础上局部表面特性。数值算例验证了该方法的有效性。
The transient field scattered from a perfect electrically conducting (PEC) ellipsoidal surface illuminated by an electromagnetic (EM) plane wave was analyzed in Chou 's work (IEEE Trans. Antennas Propag., vol. 60, no. 1, pp. 340-350, Jan. 2012), which is extended to treat a general hyperbolic surface by expressing it as an ellipsoidal one with the surface curvatures continuing into complex space. The solution allows one to model more realistic scatterers with both localized convex and concave surfaces according to the uniform geometrical theory of diffraction (UTD)-type scattering mechanisms of reflection and edge diffraction based on local surface properties. Numerical examples are presented to validate the solution.
