Goals

Physics knowledge of materials behaviors is given. It covers magnetic, dielectric and electroactive materials and their applications from electro-technical power systems to micro-electro-mechanical systems.
Basic knowledge in Electromagnetism are introduced. Energy conversion, power flow in electrical and electromechanical systems (motors, generators, sensors, power electronic devices) are so presented. The main aims are to develop semi-analytical models used in the design process and to improve skill of students for FEM simulation of electromagnetic devices.

Content

Lectures and Tutorials : Soft Magnetic Materials
• Ferromagnetism : exchange energy, anisotropy and magnetostatic
• Magnetization mechanisms : domain-wall motion, moment rotation
• Diffusion in magnetic materials and magnetic losses.

Lectures and Tutorials : Hard Magnetic Materials
• Hard magnetic materials properties : ferrite, Alnico, rare earth magnets
• Design of magnetic systems using magnets : actuators and magnetic sensors

Lectures and Tutorials : Dielectric Materials
• Electrostatic basic knowledge, Dielectric material's properties
• Electric polarization phenomenon due to electric field.
• Losses in dielectric materials.
• Breakdown field strength and partial discharges in gases.

Lectures : Electroactive materials
• Giant magnetostrictive materials, magnetic shape memory alloys.
• Piezoelectric materials
• Use of Magneto-Mechanic-Electric coupling in Microsystem's design as : piezoelectric - magnetostrictive trilayer, ...

Tutorials :
