This paper deals with a time-domain wavelet-based approach for the PEEC met
hod. Our goal is to investigate a new procedure for the formulation in time
domain of the PEEC technique able to consider Linear as well as nonlinear
circuits, By means of the wavelet transform the differential operators in t
he PEEC equations are substituted by matrices. The high sparsity of these m
atrices makes this procedure effective for reliable time domain simulations
.
