Electromagnetic interference protection structure

A detector structure, comprising:

• a layer of graphene;
• a sensor for detecting energy impinging on the structure in the infrared and optical frequency band, the sensor being disposed behind the layer of graphene;
• an electronics section disposed behind the sensor for processing electrical signal produced by the sensor in response to the sensor detecting the infrared and optical energy;
• wherein the layer of graphene disposed passes the infrared and optical frequency bands to the sensor while inhibiting electromagnetic energy outside of the infrared and optical frequency bands from passing to the electronics section.

A detector structure, comprising:

• a 2-dimensional crystalline planar structure of the graphene;
• an array of sensors disposed behind the 2-dimensional crystalline planar structure of the graphene for detecting energy impinging on the detector structure in the infrared and/or optical frequency band;
• an electronics section disposed behind the array of sensors for processing electrical signal produced by the array sensor in response to the array of sensor detecting the infrared and/or optical energy;
• and
• wherein the 2-dimensional crystalline planar structure of the graphene passes the infrared and/or optical frequency bands to the sensor array while inhibiting electromagnetic energy outside of the infrared and/or optical frequency band from passing to the electronic section.
