ABSTRACT
Abstract:
The TLM method has the advantage that electromagnetic field equations are modeled by means of transmission line networks. Therefore, embedding of lumped and distributed devices in the TLM mesh is straightforward since the equivalent models of those can be connected to a TLM node using transmission lines. In this thesis, several techniques for spreading the device over a finite volume corresponding to its physical size are presented. In order to connect the device to the TLM network, the equations governing the devices are solved using a central difference scheme. However, this approach is time consuming and requires extra programming effort, especially for a nonlinear active device. The connection between SPICE and TLM enables us to overcome the above-mentioned problems. The main benefit of such a hybrid system is to take advantage of the efficient combination of their respective strengths to solve complex electromagnetic problems and enhance computational efficiency.
