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.
