“…We chose to be on the observation plane parallel to the axis of the cylinder where the error of the numerical anisotropy is maximal (angles ±ᴨ/2). The incidence field Ez is a plane wave and the exact solution of the Mie scattering problem is known [25].…”

“…Based on these remarks, we present in the following the new "Element Oriented Model" (EOM) in electromagnetism [25]. This model allows us to formalize the electromagnetic equations in a similar way as object-oriented numerical computation.…”

“…Furthermore, the topological approach allows us to establish new dynamic visualizations of the basic laws of the electromagnetic theory [25] which is, from a didactic point of view, very important, these representations root the theory and make it assimilation simpler. This approach is the basis of our proposal for the object-oriented model.…”

“…Using this kind of space-time objects and knowing that Maxwell's equations contain a certain number of symmetries and conservation laws that could be broke or modified by discretization, we propose a set of equations where conservation laws remain preserved in a discretized zone when they are formulated near the borders of this region. Thus, they do not depend on the space metric and are invariable under homeomorphism (for more details on the calculation process, readers can refer to [25]).…”

The web has spurred our imagination as to how education can be drastically transformed and improved through the adoption of Information and Communications Technology (ICT) and the use of simulations quickly became a wildly disputed topic. This kind of simulations are considered as a significant pedagogical innovation especially in the electromagnetics course where it is possible to concretize , via a set of interactive simulations, some experiments that are inaccessible in real life. The aim of interactive simulations is to enhance the student’s understanding by providing him a meaningful insight into the studied notions, phenomena, concepts, laws and models. The design of didactic simulations is constrained by both technological choices, learning theories and numerical models which should guarantee a minimal execution time, a better stability and an acceptable precision. Our goal in this work is to design didactic simulations for electromagnetism using a numerical Element Oriented Method (EOM). The proposed EOM meets the needs of speed, accuracy and ensure bet-ter dynamical and visual interpretations of the basic laws of electromagnetic. Moreover, these applications are not only available for traditional training in the classroom but also for new training platforms provided by digital technologies such as web-based training, e-learning and m-learning.

Vision plays an important role in improving comprehension and perception of electromagnetic fields. One reason electromagnetic fields is considered by students to be a difficult course is because electromagnetic fields, being vector functions of space and time, unlike mechanics, which deals with concrete objects, are conceptually abstract and hard to visualize. Invisibility is a considerable obstacle on the way to understanding physical phenomena. To overcome this obstacle, we present in this paper some interactive simulations mainly developed for educational purposes in electromagnetics in order to facilitate the understanding of field theory and vector analysis. This interactive simulations can be used as a virtual laboratory where students can explore the solutions on their own efforts and in every detail, hence, deepening their understanding of the subject matter.
