ELECTRICAL ENGINEERING EDUCATION

CHAPTER 11: Electromagnetic Field and Propagation.

The objectives:

- To learn about the behavior of electromagnetic waves
- To learn the behavior of electromagnetic waves when interact with different media; conductor, dielectric (lossy / lossless), and free space.
- To learn about Poynting vector; to determine the power of electromagnetic field.

Part 2 - Helmholtz Equation & Propagation

You will learn the basic concept of propagation for electromagnetic wave using derivation of Helmholtz equation. You can see how E-Field and H-field co-exist for time varying field and how we can express the wave in term of mathematical expression.
