Implementations may include: a metal-containing plate configured to be directly attached to a rear surface of a mobile electronic device where the metal-containing plate includes a coating. The metal-containing plate may be configured to deflect, absorb, or reflect electromagnetic radio frequency radiation emitted by the mobile electronic device away from a user of the mobile electronic device. ## Claims ### Claim 1 A device used with a mobile electronic device, the device comprising: a metal-containing plate configured to be directly attached to a rear surface of a mobile electronic device, the metal-containing plate comprising a coating; wherein the metal-containing plate is configured to deflect, absorb, or reflect electromagnetic radio frequency radiation emitted by the mobile electronic device away from a user of the mobile electronic device and; wherein the metal-containing plate comprises a perimeter that forms any closed shape. ### Claim 2 (depends on 1) The device of claim 1, wherein the metal-containing plate is one of smaller than, coextensive with, or the same dimension as a perimeter of the rear surface of the mobile electronic device. ### Claim 3 (depends on 1) The device of claim 1, wherein the metal-containing plate comprises a non-planar surface on a largest surface of the metal-containing plate. ### Claim 4 (depends on 1) The device of claim 1, wherein the metal-containing plate comprises a material selected from the group consisting of copper; gold; silver; platinum; nickel; aluminum; ferrite; shungite; any radio frequency attenuating, absorbing, or reflecting material; and any combination thereof. ### Claim 5 (depends on 1) The device of claim 1, wherein the coating is selected from the group consisting of an electroplated coating, an electroless plated coating, a paint including a wet or dry carrier, a rubber coating, a metal coating, a metal filing coating, a magnetic coating, a clear coating, a ceramic coating, a powder coating, and any combination thereof. ### Claim 6 (depends on 1) The device of claim 1, wherein the metal-containing plate comprises two or more layers wherein one of the two or more layers is either a metallic material or a non-metallic material and a second one of the two or more layers is either a non-metallic material or a metallic material. ### Claim 7 (depends on 1) The device of claim 1, further comprising a coupling mechanism on the metal-containing plate, the coupling mechanism configured to couple the metal-containing plate directly to the rear surface of the mobile electronic device, the coupling mechanism selected from the group consisting of an adhesive, hook and loop fasteners, screws, snaps, double sided tape, polymers, suction cups, magnetics, and any combination thereof. ### Claim 8 A device used with a mobile electronic device, the device comprising: a plate configured to be directly attached to a rear surface of a mobile electronic device or coupled between a cover and the rear surface of the mobile electronic device, the plate comprising at least two portions; and a coating, wherein the coating is selected from the group consisting of an electroplated coating, an electroless plated coating, a paint including a wet or dry carrier, a rubber coating, a ceramic coating, a metal coating, a metal filing coating, a magnetic coating, a clear coating, a powder coating, and any combination thereof; wherein a material of at least one of the at least two portions of the plate is configured to deflect, absorb, or reflect electromagnetic radio frequency radiation emitted by the mobile electronic device away from a user of the mobile electronic device. ### Claim 9 (depends on 8) The device of claim 8, wherein the plate comprises at least two metal-containing portions. ### Claim 10 (depends on 8) The device of claim 8, wherein the at least two portions of the plate are coupled together through a non-metallic portion or metallic portion. ### Claim 11 (depends on 8) The device of claim 8, wherein the non-metallic portion is selected from the group consisting of a binder, a support, a plastic support, a rubber support, a polymer support, a wood support, a carbon fiber support, a resin support, a glass reinforced epoxy laminate support, an adhesive, a glue, a molding compound, and any combination thereof. ### Claim 12 (depends on 8) The device of claim 8, wherein at least one of the at least two portions of the plate comprises two or more layers wherein one of the two or more layers is either a metallic material or a non-metallic material and a second one of the two or more layers is either a non-metallic material or a metallic material.
