Field analysis in tubular coilguns by wavelet transform

In this paper, a new method for the field analysis in tubular coilguns by wavelets on the interval and equivalence theorem is proposed. By adopting the equivalence theorem, the computational domain is restricted to the conductive region while expanding the space variables by wavelets on the interval. We obtain a storage of the unknowns in a matrix form instead of the usual vector form yielding a savings of memory storage and CPU times. The solution is then obtained by a standard time-stepping method.
