Discussion Overview

The discussion revolves around the Lorentz gauge condition, its definition, and its practical applications, particularly in relation to electromagnetic potentials and their behavior in real-life situations.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests a simple explanation of the Lorentz gauge condition and its practical examples, specifically questioning its ability to "carry" two different frequencies simultaneously.
  • Another participant references an external source, explaining that the Lorentz gauge relates to the arbitrary nature of electromagnetic potentials and how it prescribes a method for selecting these values.
  • A different participant mentions encountering the Lorentz gauge condition in a patent, suggesting its application in a transmitter operating at high frequency with a sub-carrier at a lower frequency, indicating a potential real-world use case.
  • One participant dismisses the notion of carrying two different frequencies as nonsensical.

Areas of Agreement / Disagreement

There appears to be disagreement regarding the interpretation of the Lorentz gauge condition's application, particularly concerning the concept of carrying multiple frequencies. Some participants provide differing views on its practical implications.

Contextual Notes

Participants express varying levels of understanding and interpretation of the Lorentz gauge condition, with some assumptions about its applications remaining unresolved.

Can someone explained in simple language what is Lorent'z gauge or Lorent'z gauge condition, and can you give me example from practice or real life, can it maybe "carry" 2 different frequency at once let say.
 
Physics news on Phys.org
You've looked at this already? http://en.wikipedia.org/wiki/Lorenz_gauge_condition

Just like energy has an arbitrary zero point, the electromagnetic potential also has an arbitrary zero. (meaning, you can add some constant to the energy at every point and not change a thing.) But the electromagnetic potential has more wiggle room in its arbitrary factor, such that you can add various functions to the potential and not change the physics at all. The Lorenz gauge proscribes one way to choose the values of these arbitrary functions.

"carry" 2 different frequency? That makes no sense whatsoever.
 
Thanks Khashishi

Sorry I saw on US patents one invention who use lorent'z gauge condition, and in description it says that transmitter operate at high frequency and sub carrier at lower, I can research again and sand you a link.
 
no need for that
