"A short while ago, I explained why your Faraday cage doesn`t separate E and H as you claim." There are many examples of Faraday screens at work removing the E field while allowing H field coupling. I chose the Faraday sdreens in medium wave broadcasting used to reduce radiation of harmonics of the channel frequency. More numerous examples abound. These are the Faraday screens used in isolation power transformers between primary and secindary coils to prevent transient high-frequency energy coupling. My 19th edition of the ARRL Antenna Book contains yet another example on page 14-2 which says: "Fig 2 - Shielded loop for direction finding. The ends of the shielding turn are not connected, to prevent shielding the loop from magnetic fields. The shield is effective against electric fields. Best regards, Richard Harrison, KB5WZI |
