Abstract :
It is shown that retardation effects, due to the finite speed of electromagnetic interactions, play a significant role for PC-board interconnects. It is demonstrated that in some cases errors of more than an order of magnitude result in some frequency components when retardation is neglected. Extensions to a circuit simulator are introduced that make it possible to do retarded circuit simulation. Specifically, an algorithm to extend SPICE-level simulators to include retardation is presented. Comparisons with analytical equations, the method of moments, and with measurements show good agreement.<>
