Abstract
The issue of passivity of discrete approximations to electromagnetic systems that are passive in their continuous form is examined in this paper. Discrete model passivity is important both for numerical stability purposes and for the development of passive reduced-order models of the system for use in network-oriented circuit simulators. It is shown that the passivity of the semi-discrete model obtained from the numerical discretization of the spatial derivatives in Maxwell's equations can be examined in terms of the properties of the resulting matrix representations of the curl operators. In particular, a set of constraints on these operators is derived which, if satisfied, will guarantee the passivity of the state-space representation of the semi-discrete electromagnetic model.
