Overview

This course aims to provide the student with the basic concepts of electromagnetic radiation, the various conservation laws, and the deduction of the laws of light as an electromagnetic wave. It covers the topics of Maxwell's equations, the propagation of electromagnetic waves and waves in bounded regions, radiation emission, and electrodynamics.

Intended learning outcomes

By studying this course the student will be able to:1- Explain the laws of conservation of charge, energy and momentum in the presence of electromagnetic fields.2- Explain the meaning of Poynting vector and Maxwell extensions.3- Explain how Newton's third law applies to electromagnetism.4- Analyze the problems of boundary conditions and Maxwell extensions.5- It connects the laws of reflection and refraction of light with the electrical and magnetic properties associated with it.6- Explain radiation from an oscillating dipole.7- Calculate the total radiated power of a half wave antenna.
