结果表明，边界波处理方法中的基尔霍夫和瑞利-索末菲理论，分别与直边衍射的严格电磁理论解中的电场分布和磁场分布符合较好。
The field distributions given by Kirchhoff theory and Rayleigh-Sommerfield theory are studied respectively, and further comparisons with the exact electromagnetic theory are also given.
索末菲关于波的展开理论证明，球面波可以展开为平面简谐波的叠加。
Sommerfeld's wave expansion theory demonstrates that a spherical wave can be expanded as the superposition of plane simple harmonic waves.
