Walking sinusoidal as you follow a RF Standing Wave?

Click For Summary

Discussion Overview

The discussion revolves around the nature of electromagnetic (EM) waves, specifically in the context of following a radio frequency (RF) standing wave while walking. Participants explore whether it is feasible to walk along a sinusoidal path that corresponds to the wavelength of an RF signal, and the implications of standing waves versus propagating waves.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant recounts an experience where walking towards a target while using RF locator equipment resulted in a sinusoidal path, questioning if this is possible with the right frequency.
  • Another participant asserts that EM waves travel in straight lines and that the sinusoidal representation is merely a graphical depiction of amplitude variations, not indicative of the wave's travel path.
  • A participant clarifies that a standing wave is characterized by stationary oscillations and does not propagate, suggesting that it exists between two points, such as a transmitter and a reflective surface.
  • Further elaboration on standing waves includes the concept of nodes being fixed in the stationary oscillation, raising questions about the physical setup required for such a phenomenon.

Areas of Agreement / Disagreement

Participants express differing views on the nature of EM waves and standing waves, with no consensus reached regarding the feasibility of walking a sinusoidal path in relation to RF signals.

Contextual Notes

The discussion highlights potential misunderstandings about the propagation of EM waves versus the characteristics of standing waves, with some assumptions about the physical context remaining unexamined.

A friend who was in Civil Air Patrol once told me he was using some RF Locator equipment and was "homing in" on a target.

His walking path to the target was sinusoidal because of the wavelength of the frequency used. He said he was literally walking the wave....

Standing wave, I assume?

Or was his imagination getting the better of him?

Is this possible with the right frequency?

EM waves travel in straight line (unless they are continuously being reflected/refracted/scattered) and not sinusoidal. If you want to follow an EM wave you have to travel in straight line with the speed of light. The sinusoidal shape you see in a graphical representation of wave is representing the amplitudes of the electric and/or magnetic field at the various points in space, it is not how the EM wave travels in space.

A standing wave is not propagating...It's a stationary oscillation of the object (of the magnetic and electric field in case of EM waves).
Then what Delta2 said

That standing wave is between 2 points? Could it be between a transmitter and a mountain, water tower, etc, etc?

The nodes are/or can be fixed in that stationary oscillation?
