Application of Petri-Nets to Modelling Interconnected Electromagnetic Waveguide Junctions for Analogue Computing Applications

Petri-Nets (PNs) are a graphical modelling system that has found applications in both research and industry including asynchronous computing. In this work, we present our work on implementing PNs to model the propagation of transverse electromagnetic (TEM) pulses within multiple interconnected waveguide junctions. The ability of PNs to represent multiple reflections in waveguide junctions is demonstrated, an important aspect for modelling systems of cascaded waveguide junction or waveguide junctions where some ports are terminated with perfect electric conductors.
