Lessons : 18 h TD : 10 h TP : 3 h Project : 0 h Total : 31 h
Co-ordinator : Sylvain Girard
Prerequisite
Basic mathematics (complex numbers, trigonometric functions and partial derivatives); Basics in electromagnetism;
Course Objectives
Basic concepts and main properties of wave phenomena in the engineering sciences:
- ultrasonic acoustic waves for measurement and sensors;
- electromagnetic waves (RF / HF and light) in free propagation or in a dielectric medium;
- antennas and propagation link budget;

Applications:
- non contact measurements (telemetry, radar);
- telecommunications (RF / HF or optical);
Syllabus
