Abstract :
A new transmission line matrix (TLM) formulation in terms of magnetic flux pulses is presented for the numerical modeling of time-varying electromagnetic media. After redefining the Thevenin theorem in terms of magnetic flux and electric charge, this conceptually new approach is used to develop a dynamic generalized TLM node for the modeling of electromagnetic-wave propagation through time-varying media. Different specific implementations of the generalized node show the successful behavior of the node proposed in this paper.
