Where This Module Goes

Faraday’s law, displacement current, and the full set of Maxwell’s equations, then the uniform plane wave they predict: its properties, its polarization, and what happens when it meets a boundary.

Chapter 8: Dynamic Fields

  1. I can articulate the significance of the displacement current and calculate it, given a time-varying electric field.
  2. I can articulate the meaning of and calculate the relaxation time for a variety of materials.
  3. I know the forms of Maxwell's equations for time-varying fields and use them to calculate electric and magnetic fields for a variety of physical systems.

Chapter 9: Plane Waves (9.1-9.4)

  1. I understand the process of decoupling and finding solutions for Maxwell's equations for dynamic fields.
  2. I can articulate what a Uniform Plane Wave (UPW) is and describe key properties that relate the electric and magnetic field.
  3. I can calculate the electric and magnetic fields for a UPW.
  4. I can articulate the concept of polarization and determine the polarization for various UPWs.

Chapter 9: Plane Waves (9.5-9.5)

  1. I can determine the reflection and transmission of UPW at a boundary for Transverse Electric (TE) and Transverse Magnetic (TM) waves, using boundary conditions.
