### EMT - CHAPTER 11 - ELECTROMAGNETIC WAVES AND PROPAGATION (Teaching Videos)

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.

Part 2a: Helmholtz Equation and Propagation of Plane waves (Example):

- 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.

Part 3: Plane wave in Lossy Media:

In part 3, you will learn the behavior of plane wave when going through the lossy media (dielectric - Lossy). The example is also given for more explanation.

Part 4: Plane wave in Lossless and free space media:

In part 4, you will learn the behavior of plane wave when going through a lossless media (dielectric - Lossless) and free space.

Part 5: Plane wave in conductor:

In part 5, you will learn the behavior of plane wave when going through a conductor.

Part 6: Power and Poynting Vector

In part 6, you will learn to determine the power for electromagnetic wave using Poynting Vector.
