Claim Text:
1. A device configured to shield a user from electromagnetic radiation emitted by an electronic device having a back side, a front side, and multiple lateral sides, wherein the electromagnetic radiation has a predominant range of frequencies between about 450 MHz and about 2.5 GHz, the device comprising: a body including two or more layers of material, wherein a first layer of material has properties of absorption of the electromagnetic radiation in the predominant range of frequencies between about 450 MHz and about 2.5 GHz, wherein a second layer of material has properties of deflection of the electromagnetic radiation in the predominant range of frequencies between about 450 MHz and about 2.5 GHz, wherein the two or more layers of material attenuate the electromagnetic radiation in the predominant range of frequencies by at least 25 dB, wherein the second layer of material has properties of deflection of the electromagnetic radiation such that the electromagnetic radiation is attenuated by at least 60 dB through the second layer of material, and wherein the body is arranged to be disposed near the back side of the electronic device.
