Enhancing photocurrent transient spectroscopy by electromagnetic modeling [PDF]
The shape and duration of photocurrent transients generated by a photoconductive switch depend on both the intrinsic response of the active material and the geometry of the transmission line structure. The present electromagnetic model decouples both shape forming contributions.

Complete transformer model for electromagnetic transients [PDF]
A complete, three phase transformer model for the calculation of electromagnetic transients is presented. The model consists of a set of state equations solved with the trapezoidal rule of integration in order to obtain an equivalent Norton circuit at the transformer terminals. Thus the transformer model can be easily interfaced with an electromagnetic

Synchronous Machine Modeling Precision and Efficiency in Electromagnetic Transients [PDF]
This paper presents various synchronous machine models implemented in the computation of electromagnetic transients. This paper proposes new models for achieving better computational efficiency while maintaining precision. In addition to simple infinite bus analysis, the machine models are also compared for a more sophisticated and practical case study.
