Abstract
Described herein is electromagnetic shielding that is configured to attenuate electromagnetic interference (EMI) by at least a threshold amount when the EMI has a frequency within a predefined frequency range. The electromagnetic shielding includes a layer of metal, such as aluminum foil, and a layer of thermoplastic polymer fabric (such as woven polyethylene fabric), where the electromagnetic shielding has several apertures that extend therethrough. The electromagnetic shielding is at least partially draped over electronic equipment that is to be shielded from EMI.
Claims20
A data center comprising:
- a piece of electronic equipment;
- and
- electromagnetic shielding that is draped over the piece of electronic equipment to attenuate electromagnetic interference (EMI) within a frequency range by a threshold amount, where the electromagnetic shielding comprises:
- a layer of metal;
- a layer of thermoplastic polymer fabric that is bonded to the layer of metal, where the layer of thermoplastic polymer fabric provides a structural backing for the layer of metal;
- a second layer of metal, where the layer of thermoplastic polymer fabric is positioned between the layer of metal and the second layer of metal, and further where the second layer of metal is bonded to the layer of thermoplastic polymer fabric;
- and
- apertures that extend through a thickness of the electromagnetic shielding, wherein the apertures are perforations that extend through the layer of metal, the layer of thermoplastic polymer fabric, and the second layer of metal.
A method comprising:
- positioning a piece of electronic equipment in a data center;
- and
- draping electromagnetic shielding over the piece of electronic equipment to attenuate electromagnetic interference (EMI) within a frequency range by a threshold amount, where the electromagnetic shielding comprises:
- a layer of metal;
- a layer of thermoplastic polymer fabric that is bonded to the layer of metal, where the layer of thermoplastic polymer fabric provides a structural backing for the layer of metal;
- a second layer of metal, where the layer of thermoplastic polymer fabric is positioned between the layer of metal and the second layer of metal, and further where the second layer of metal is bonded to the layer of thermoplastic polymer fabric;
- and
- apertures that extend through a thickness of the electromagnetic shielding, wherein the apertures are perforations that extend through the layer of metal, the layer of thermoplastic polymer fabric, and the second layer of metal.
A method comprising:
- supporting electromagnetic shielding from a support mechanism that is coupled to a ceiling of a building that retains electronic equipment, where the electromagnetic shielding comprises:
- a layer of metal;
- a layer of thermoplastic polymer fabric that is bonded to the layer of metal, where the layer of thermoplastic polymer fabric provides a structural backing for the layer of metal;
- a second layer of metal, where the layer of thermoplastic polymer fabric is positioned between the layer of metal and the second layer of metal, and further where the second layer of metal is bonded to the layer of thermoplastic polymer fabric;
- and
- apertures that extend through a thickness of the electromagnetic shielding, wherein the apertures are perforations that extend through the layer of metal, the layer of thermoplastic polymer fabric, and the second layer of metal;
- and
- draping the electromagnetic shielding over a piece of the electronic equipment.
