Hi Guys,
As you know high frequency microwaves are subject to rain fade and atmospheric attenuation.
When it comes to extremely low frequencies (3 to 300Hz), even a Faraday cage is unable to block it. Is there any material or phenomea which attenuates, absorbs or reflects these signals. For example, rainfade for high freq. microwaves and an analogical phenomena for extremely low frequencies.
Kind Regards.
