Electromagnetism and Electromagnetic Devices


The area of Electromagnetism and Electromagnetic Devices focuses on electromagnetism research applied to engineering. Lines of research in this area can be classified as:

  • Computing research on calculation of magnetic fields, with the development of software used to calculate electrical, magnetic and electromagnetic fields in one, two and three dimensions.
  • Experimental research on characterization of magnetic materials, with emphasis on the study of losses, in addition to studies concerning electrical drives and magnetic vibrations.
  • Studies related to electromagnetic compatibility, including the development of calculating tools and experimental procedures.

Electromagnetic Compatibility and Electrical and Electronic Systems

Electromagnetic Compatibility (EMC) has had significant importance in the electrical and electronics industry. Many of the electrical and electronic equipment inherently generate electromagnetic interference (EMI) and they are also susceptible to this interference. Therefore, projects have to be carefully designed in order to ensure electromagnetic compatibility and guarantee the equipment complies with standards.

Computing Research in Field Calculation

Development of software to calculate magnetic fields.

Field Equation coupled to 2D Electric Circuits.

Modelling equations of electromagnetic fields represented by two-dimensional finite elements coupled to electric equations of feeding electronic converters.

3D Field Calculation using Edge Elements.                                        

Study and implementation of edge finite-element method; coupling to electric circuits; new formulations; complex formulation.

Methods for Loss Evaluation in Magnetic Material.

Study of mathematical models to describe magnetic hysteresis curves (PREISACH, JILES- ATHERTON,…) and their respective coupling to field calculation using finite elements and edge elements. Experimentation is also included.

Numerical Methods in Electromagnetic Compatibility

Study of numeric methods to model electromagnetism problems, specifically the Transmission Line Matrix Method (TLM), which represents the simulation of wave propagation in the time domain. The study is applied to a wide range of electromagnetism fields, such as microelectronics, telecommunications, electromagnetic compatibility and bioelectromagnetism, and can be used in problems involving non-homogeneous, non-linear, anisotropic means and complex geometry.
