Effects of Electron/Ion Particle Spray on Antennae

AI Thread Summary
The discussion revolves around the impact of electron and ion particle sprays on antenna performance, specifically a patch antenna calibrated for 300 MHz. Observations indicate a significant voltage drop followed by a spike in signal, correlated with the timing of the particle spray, but the frequency of this signal is much lower than expected. Participants are questioning whether the particle spray is genuinely affecting the antenna's response or if other factors might be responsible for the low-frequency signal. The antenna is situated near a target being struck by small iron particles traveling at high speeds. The inquiry seeks clarification on the potential effects of such environmental conditions on antenna behavior.

I was wondering if an antenna could pick up some sort of signal if it was exposed to a spray of electrons or ions. For instance I have a patch antenna calibrated for 300 MHz. The patch antenna was placed in an environment where it could be getting sprayed by a wave of electrons followed by a wave of ions. In the antenna response I see a very strong signal voltage drop follow by a strong spike that is temporally correlated with when it would be getting sprayed, but the frequency of this signal is orders of magnitude below 300 MHz. Is this a possible effect of the particle spray, or is it more likely that something else is the cause of this low frequency signal showing up on a high frequency antenna. Any help would be GREATLY appreciated!

Is this something that is actually happening? If so, what kind of environment is your antenna located in?
 
The antenna is located near a target that is being impacted by small iron particles traveling around 30 km/s

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
