Needless to say, the method of integral equations and the Green's function technique can also be developed. 无庸赘言，也可以发展积分方程法或格林函数技术。
Since the Green's function is based on Sommerfeld integration, the MLFIPWA has the advantage of being directly expanded into layered medium problems. 由于其格林函数直接基于索末菲尔德积分，具有可以直接推广到分层媒质问题的优势。
