Knowledge of unwanted electromagnetic phenomena, interferences, understand unwanted coupling and to be able to find possible interference mitigation measures.
An electronic system that is able to function compatible with other electronic systems and does not produce or be susceptible to interference is said to be electromagnetic compatible with its environment. The objective of this course is to recognize and understand Electromagnetic Compatibility (EMC) problems and to design electronic systems for EMC. Example of non-EMC are the mobile telephone (GSM) disturbing a pacemaker or electronic equipment in a plane, or the broadcast station disturbing the motor management system of a car. The following subjects are part of the course: transmission lines, radiation and coupling, parasitic elements of components, crosstalk, filters, shielding. Several demonstrations will be presented in most lectures.
Assumed previous knowledge:
- Transmission lines: telegraphist's equation, types of lines, cable parameters, skin effect, reflections, terminations, transfer function, standing waves, reflectometry.
- Waveguides: TE and TM modes, propagation constant, losses, applications.
- Planar waveguides: modes, propagation constant and losses in strip lines; applications.
- Antennas and propagation: radiation by an elementary dipole, antenna parameters and radiation patterns, types of antennas; antenna arrays and its properties; attenuation of radio waves, link budget, refraction and shadowing, Doppler shift, fading and spreading by multipath transmission
: the student is expected to have sufficient understanding of models, electronic components and basic circuits.
: Maxwell equations, time− and frequency−domain, differential and integral form, Poynting theorem; scalar− and vector potentials; wave equation, electromagnetic waves in media, plane wave reflection and transmission at interfaces; guided waves, dielectric waveguides; dipole radiation, antennas; transmission lines
Introductory course on communication systems
: Analog modulation and demodulation systems, digital modulation and detection techniques and systems, and the performance analyses of these systems in the presence of noise.
