Visualization of fields in waveguides

Click For Summary
SUMMARY

The discussion focuses on the visualization of electromagnetic (EM) fields in waveguides, specifically addressing the longitudinal behavior of E and H fields in Transverse Magnetic (TM) and Transverse Electric (TE) modes. Participants highlight the challenge of intuitively understanding these fields compared to the simpler Transverse Electromagnetic (TEM) mode. A recommended resource for further reading is the Feynman Lectures on Physics, which includes a chapter dedicated to waveguides, providing foundational insights into this topic.

PREREQUISITES
  • Understanding of electromagnetic wave propagation
  • Familiarity with waveguide modes (TM, TE, TEM)
  • Basic knowledge of field visualization techniques
  • Access to the Feynman Lectures on Physics
NEXT STEPS
  • Study the chapter on waveguides from the Feynman Lectures on Physics
  • Explore visual simulation tools for electromagnetic fields in waveguides
  • Research the mathematical representation of TM and TE modes
  • Investigate practical applications of waveguides in telecommunications
USEFUL FOR

Students of physics, electrical engineers, and professionals working with waveguide technology who seek to deepen their understanding of electromagnetic field behavior in various waveguide modes.

TL;DR
Visualization of fields in waveguides
Can someone provide me intuitive visualization of how E or H field can be longitudinal in a waveguide (TM/TE)? TEM is easy to visualize, but how EM wave can behave like sound in a waveguide (constant phase and amplitude plane in the same direction)?
