SAR shields

["Jean-Francois, Stephane" <stephane_jeanfrancois@MERCK.COM>]

I received by e-mail an add regarding SAR (Specific Absorption Rate) shields

for cell phones. They claim that these shields were tested using FCC

standards. Any validity to these results ? Any independent results ? The

marketing name makes no sense but I would like to know how it is suppose to

work. I am not an expert in cell phones (I use a lot of gadget but cell

phone is not one of them) but I think that modern cell phones have variable

emitting power depending on the signal reception. Can this shielding work,

as the cell phone will try to compensate for a lost of signal (I presume

interference by the shielding but I don't know the facts, they claim no

changes in cell communications) by emitting stronger ? Am I out of the track

by saying this ? Any other sources of info on this shielding ? They claim

that they use the same technology as stealth planes, that is absorbing

signals and not reflecting them. How can you transmit if you absorb the

signal ?

I am a rookie in radiofrequencies and my courses on wave transmission are

far in the back of my mind, so please excuse my "fundamentals questions" :-)
