小波分析结合矩量法求解方环天线的电流分布

Current solutions to a square loop by using the wavelet and the method of moment

将小波分析与矩量法结合起来 ,分析求解了方环天线的电流分布 .用小波基代替矩量法中的基函数和权函数 ,使矩量法中与算子相对应的矩阵变成大量元素为零的稀疏矩阵 ,从而大大减少了计算量 .

The wavelet and the method of moment (MOM) are combined to analyze and calculate the current distributions on a square loop, and the usual expansions and weighting functions in MOM are replaced by wavelet expansions, which makes the impedance matrix sparse. Therefore the calculating time is reduced, and the results agree well with those of MOM.
