**CHAPTER 11: Electromagnetic Waves 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 and Propagation of Plane waves:**

- 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.
