摘要

The modelling of fields in the time domain describes the evolution of physical quantities in a natural way. Transient phenomena, nonlinear and dispersive behavior, the characteristics of systems with moving boundaries or with time dependent properties are best described in the time domain. For electromagnetic field modeling numerous techniques have been developed. The modelling of fields and networks in the time domain is highly attractive since it describes the evolution of physical quantities in a natural way. Time domain modeling is especially advantageous in the case of transient electromagnetic fields, fields in nonlinear, dispersive or time-dependend media or in regions with moving boundaries. One of the main advantages of time-domain modelling of electromagnetic fields is the local dependence of the field variables on space as well as on time. Within discretized space and time the state of the field in a given point and at a given time depends only on the field states of the neighbouring points at previous times. This allows a highly parallel computation of the time evolution of the discretized field.
