Abstract :
This paper presents two new transfer matrices for an inverse potential problem using boundary element methods. The condition numbers of the new transfer matrices are compared with that of the conventional transfer matrix through numerical examples. It is shown that the condition number of the new transfer matrices may be several orders of magnitude smaller than that of the conventional one. The regularized solutions achieved by using the new transfer matrices are also shown to be better than the usual one
