Abstract :
In this paper we present an expression of the spectra and pseudospectra of the waveform relaxation operator in the solution of the steady state response of linear circuits under periodic excitation. We show that the convergence of a relaxation-based algorithm can be safeguarded if the maximum value of the spectral radii for a series of matrices derived from the system is less than one. A numerical example is provided to show the spectra and pseudospectra of an iterative scheme applied to a linear circuit under periodic excitation
