  • Purpose This paper aims to explore a new approach for time-domain modelling of interconnects with highly oscillatory modulated sources.

    Design/methodology/approach The paper uses an asymptotic method in conjunction with the Green’s function of the telegrapher’s equations. The Green’s function is expressed as a series of rational functions in the Laplace domain and are converted to pole-residue form, thereby enabling time-domain implementation.

    Findings The results indicate that the method is accurate for modelling interconnects when wide-varying frequencies are present in the sources.

    Originality/value The technique is important in circuit design for assessing signal integrity and in electromagnetic compatibility testing.
