Counter Frequency Work

AI Thread Summary

A frequency counter is a device used to measure the frequency of an input signal, providing essential data for various applications in electronics and telecommunications. Understanding its operation involves recognizing how it counts the number of cycles of a signal over a specified time period. There are various DIY kits available for building frequency counters, starting at approximately $29.95, which can be found through online searches. For a more comprehensive introduction, a Wikipedia page on frequency counters offers valuable insights. Overall, frequency counters play a significant role in electronic measurement and experimentation.

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...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

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...
