Currently, most of electromagnetic simulators are based on the solution of Maxwell's equations or their equivalent forms. These simulators have benefited from the rapid evolution of the computer power that has compensated the rapid increase of the structure complexity and size to be simulated. However, the computer power increase can no longer compensate the future demands for larger size and more complex problems. In spite of much effort made to reduce electromagnetic calculations, the difficulty to take such challenging complex problems requires the quest for an important methodological breakthrough. The method called "enactive", proposed in these works, is an atypical approach to model dynamic systems of a natural environment and its simulation in a system of virtual reality. Coming from the modelling of multi-agent systems, it offers a specific method for modelling such complex systems where many phenomena must interact in multiple ways, at different space and time scales. We wish to follow the evolution of an electromagnetic wave and its possible interactions with objects in an environment in virtuo, i.e. in a virtual laboratory (virtuoscope). In this context, this work is interdisciplinary and combines the tools and techniques of virtual reality to model electromagnetic phenomena. In addition, phenomena are modelled by autonomous entities that interact. Therefore, our model must be based on both aspects a rigorous definition of entities, namely waves and media, and interactions that may occur to reconstitute "real" electromagnetic phenomena in a virtual environment. Also, we have no means to verify or validate our model other than by experiments. In a way, we make a bet, a challenge, to succeed in building an electromagnetic enactic system. For this, we have developed some scenarios of electromagnetic environments, followed by the development of two models, one unidimensional and one bidimensionnal. Results are compared to more conventional and appropriate methods or to the theory when it is possible.
