L 7.4,8.1-- Plane Waves Lossy Media

  • Due Nov 18, 2019 by 11:50am
  • Points None

Questions of the Day:

  • Explain plane wave reflection at normal incidence. 
  • How do you calculate the following values for  a plane wave normally incident on a layered material (2-3 layers, or more) using the Smith Chart:
    • Reflection coefficient (anywhere in the model)
    • Transmission coefficient (anywhere in the model)
    • E,H fields (including their magnitudes, polarization, and direction of propagation, be able to write their equations) (anywhere in the model)
    • How do you handle boundaries terminated by perfect conductors?

Remember that the reflection and transmission coefficients here are for VOLTAGE or E field.  To find power reflection and transmission, be sure to square them!
