摘要
讨论周期小波与矩量法相结合的方法在二维电磁散射计算中的应用。以周期小波作为基函数和权函数,并利用coiflet小波的消失矩性质,求解速度较快,结果非常精确。本文分别用小波矩量法、传统的拒量法及广义多极予方法计算了一个无限长方柱在平面波照射下的电流分布,并与有关资料上的结果进行比较,吻合得很好。
In this paper coiflet periodic wavelet combined with moment method is applied for thecomputation of the electromagnetic scattering of 2-D objects. The periodic wavelet is used as basisand testing functions in the integral equations. Taking advantage of the vanishing-moment propertyof coiflet, accurate results can be obtained quite quick1y. The current distribution on an infinitely longequare cylinder illuminated by plane wave (TM case) is computed by periodic wavelet-momentmethod, conventional moment method and general multipole technology, respectively. The numericalresults are compared with previously published data, which demonstrates good agreement betweenthe result of periodic wavelet-moment methed and the published one.
