摘要

提出了完美电导体平面内任意方位半椭圆形空腔散射的半解析解法。通过在椭圆边界施加边界条件，提取出包含马修函数序列的三个独立方程。最后，利用马修函数加法定理和角马修函数的正交特性，将问题的求解简化为一个简单线性方程组的求解。本文列举了一些示例来证明所提出的解决方案的可靠性和准确性。

Scattering from a semi-elliptical cavity with arbitrary orientation placed in a perfect electric conductor plane

A semi-analytic solution for scattering from a semi-elliptical cavity with arbitrary orientation placed in a perfect electric conductor plane is suggested. By imposing the boundary conditions at an elliptical border, three independent equations containing the Mathieu functions series are extracted. Finally, the solution of the problem is reduced to the solution of a simple system of linear equations by using Mathieu function addition theorem and the orthogonal properties of the angular Mathieu functions. Some examples are presented to demonstrate the reliability and the accuracy of the proposed solution.
