An actual 'Faraday screen' or shield about 2/3rds of the way down this page:
Note: Effective for blocking the 'electric' field component and much, much less the magnetic.
Use of a Faraday Shield to prevent detuning of an oscillator coil:
Global Warming (AGW) the spectrum involved:
Chief molecular absorbers in the atmosphere are water vapour and carbon dioxide, with contributions also from ozone, methane, nitrous oxide, and others. The general atmospheric transmittance across the whole spectrum of wavelengths is also shown in Figure 4. Wavelengths used for remote sensing of the surface are chosen in windows where the atmospheric transmittance approaches 100%.
In general, atmospheric absorption tends to become stronger from the visible to the infrared. Water vapour causes most absorption in the near infrared from 0.7um to 6 um (but with C0 2 bands at 2.7 um and 4.3 um), there is strong C02 absorption around 15 um, then intense water vapour absorption takes over right through to about 1 mm wavelength
EMR (Electro-Magnetic Radiation) emitted from sun which passes through the atmosphere and is reflected in varying degrees by Earth's surface and atmosphere
Terrestrial radiation (from earth)

- Electrical Charging (due to ion embedding in non-conducting surfaces) - Single Event Upsets (high-energy particles affect semiconductor junctions in logic gates) - Radiation Hazards (permanent damage from X-rays) - Spacecraft drag and Orbital Tracking (Space lab is/was an example) - Disorienting magnetic fluctuations and discharges (disorient on-board atttitude and station-keeping compasses) - Radio interference ('desense' of ground station receivers whose antennas can 'view the sun')
**** May 19th, 1998 Loss of Galaxy IV (Galaxy 4) satellite - taking with it most pager service in North America (any paging system like PageMart's or PageNet's that used VSATs through this bird to communicate with their terrestially-located paging sites across the US) - Technical reason for loss.
