AI Thread Summary
The discussion centers on the practical blocking of the microwave auditory effect, also known as the Frey effect, particularly in the context of "voice to skull" (v2k) technology. Participants suggest various methods for blocking v2k signals, including the use of tin foil hats, EMF shielding fabric, and Faraday cages. It is noted that intelligence installations may use conductive materials to prevent eavesdropping, which could also isolate a space from such signals. The conversation emphasizes a hypothetical approach without delving into conspiracy theories. The thread concludes after addressing the question of practical solutions for blocking these signals.

TL;DR Summary
Hypothetically, if someone could send "v2k" to a person's brain, how could this v2k be blocked, practically? A tin foil hat? The EMF shielding fabric?

A Faraday cage would work -- er, yes, a literal tinfoil hat. I would think that US intelligence installations (thinking of "Havana Syndrome") already line their walls with conductive materials to prevent eavesdropping on their EM signals, and this would also work to isolate a room or house.

Note, we do not discuss conspiracy theories here.

Welcome to PF. Since Russ has answered your question, I'll go ahead and close the thread.

Thread 'Gauss' law seems to imply instantaneous electric field'

Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...

Thread 'Off resonance driving of a MW/RF cavity'

Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
