Using Induction for Wireless Apparatus'

AI Thread Summary
Induction is proposed as a method to establish a reference ground between two wireless apparatus (WA1 and WA2) that are up to 14 meters apart and moving rapidly. However, the feasibility of maintaining a reference ground between two disconnected devices is questioned, as traditional grounding typically requires a physical connection. The discussion highlights confusion over the purpose and practicality of using induction in this context. Visual aids were attempted to clarify the concept but were met with criticism regarding their effectiveness. Overall, the idea of using induction for grounding in this scenario remains unclear and potentially impractical.

Hi, I was wondering if it is possible to use induction to create and maintain a reference ground between two wireless apparatus'?

For example:

Code:
WA1                  WA2
--                    --
INDUCTION?!INDUCTION?!IN
GNDGNDGNDGNDGNDGNDGNDGND

Distance between WA1 and WA2 is at most 14 metres and distance between either WA and GND has a range of

~.01 to ~.5 metres.

WA1 and WA2 are moving rather constantly (not ALWAYS, however!) and fairly rapidly.

Not sure I'm understanding the question. How can you have a "reference ground" between two floating, disconnected devices? Seems like you'd need a wire... And why would you want such a "reference"?
 
Thanks to the wonders of MS Paint, I was able to make the situation a little more clear.

Maybe it is the Christmas spirit or something.

That drawing doesn't look very skilful and it certainly doesn't explain what you are trying to do.
Maybe wait until after Christmas and try again.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
