Analysis of periodic steady-states directly in time domain

What is it about?

Main purpose of this paper is to present a new attempt to create difference equations that enable the direct calculation of the current waveforms for circuits described by nonlinear ordinary differential equations under the basic assumption that the periodic steady-state solution with the known period exists. Resulting difference equations are nonlinear and iterative procedures have to be used. The method proposed in this paper is based on a novel numerical differential operator for the periodic function in time domain.
