Poynting Vector in Total Internal Reflection Wave (TIR)

Click For Summary
SUMMARY

The discussion centers on the Poynting vector in the context of total internal reflection (TIR) of a monochromatic plane wave transitioning from medium 1 to medium 2. Participants explore the normal and parallel components of the Poynting vector and its relationship to wave polarization. Bill asserts that the Poynting vector's calculation is straightforward and suggests that it may not depend on polarization, while also noting that circularly polarized waves change sense upon reflection. This indicates a nuanced understanding of the interaction between wave properties and reflection phenomena.

PREREQUISITES
  • Understanding of Poynting vector concepts
  • Knowledge of total internal reflection (TIR)
  • Familiarity with wave polarization types
  • Basic principles of electromagnetic wave propagation
NEXT STEPS
  • Study the derivation of the Poynting vector in different media
  • Explore the effects of polarization on wave reflection
  • Investigate the mathematical treatment of total internal reflection
  • Learn about the behavior of circularly polarized waves during reflection
USEFUL FOR

Students and educators in physics, particularly those focusing on optics and electromagnetic theory, as well as researchers interested in wave behavior during reflection phenomena.

I have the following homework problem: a monochromatic plane wave travels from medium 1 to medium 2 and experiences total internal reflection. Find the normal and parallel components of the Poynting vector, discuss the results with respect to the wave's polarization.

Now, I think that the vector just doesn't depend on the polarization, and the calculation is pretty simple, so either the problem is trivial or I don't understand something. Any hints?

A circularly polarized wave changes sense upon reflection.

Bill
