渐近分析在电磁散射中的应用

Technique of asymptotic analysis in electromagnetic scatterings

讨论了渐近分析方法在电磁散射中的应用 .主要通过把一维非线性积分I(k) =∫f(z)eikg(z) dz的求解推广到二重积分 ,解释了在计算物体表面散射场时运用渐近分析方法的过程 .该方法可以显著提高电磁散射场的计算效率和精度 .

Asymptotic analysis in Electromagnetic Scattering is discussed here. With nonlinear integral I(k)=∫f(z)e ikg(z) dz extended to double integral upon the surface, the process of asymptotic analysis method is explained thoroughly while computing electromagnetic scattering field. Using this method ,computation efficiency and accuracy can be easily achieved.
