From Galilean Covariance to Gauge Conditions: A Thermodynamic Insight to Power Integrity

Abstract

　In order to address the signal integrity issue, Galilean electromagnetism is derived from a thermodynamic approach. Attention is paid on the various regimes allowed by the quasi-static limit. It is emphasized that an abrupt transition exists between the QS-magnetic and the QS-electric regimes for which different gauge conditions on the potentials should be considered.
