Rotem Tsafrir reacted to tech99's post in the thread Weird near-field phenomenon I get in my EM simulation with
Like.
Hertz carried out what was, in effect, a race between a wave on a wire and a wave in free space *. If I am reading his paper correctly... -
Rotem Tsafrir reacted to sophiecentaur's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
Nothing with mass is actually moving faster than c. Take two sensors on the wall with their outputs taken along cables of equal length...

Rotem Tsafrir reacted to Borek's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
Imagine pointing a laser at wall - there is a red dot visible. Now start to rotate the laser - dot moves. As angles change dot moves...

Rotem Tsafrir reacted to Baluncore's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
The group velocity propagates at the speed of light. The phase velocity moves at between the speed of light and infinity. Consider a...

Rotem Tsafrir replied to the thread Weird near-field phenomenon I get in my EM simulation.That’s seems like a great explanation. Thanks a lot!

Rotem Tsafrir reacted to Swamp Thing's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
Could it be something analogous to the "superliminal scissors" thing where the point of intersection moves faster than light? Say we...

Rotem Tsafrir posted the thread Weird near-field phenomenon I get in my EM simulation in Electrical Engineering.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...

Does this help?

Rotem Tsafrir reacted to Nate Duong's post in the thread What do electric and magnetic fields look like around a dipole antenna? with Like.
It is helped, but for the visualization. Do you have any information (links, or book) in detail for this topic? if I have 2 same...

Rotem Tsafrir reacted to tech99's post in the thread What do electric and magnetic fields look like around a dipole antenna? with Like.
I think they are getting at the idea that the lines are not curved when considered over the dimensions of a typical antenna at a great...

My web protection software blocks access to your link because it has an "unmatching security certificate".

Yeah, I'm getting the same error/warning.
