Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 9:
10. A phased array comprising:
an electrically conductive layer;
a first dielectric layer over the electrically conductive layer;
a transparent electrically conductive layer over the first dielectric layer;
a second dielectric layer over the transparent electrically conductive layer;
a graphene layer over the second dielectric layer and having a perforated pattern comprising an array of elliptical holes, the graphene layer configured to emit infrared (IR) radiation in a frequency range;
first and second electrically conductive contacts coupled to the graphene layer; and
circuitry configured to
apply a voltage signal between the first and second electrically conductive contacts,
change the voltage signal to selectively set phase change between the IR radiation emitted from adjacent elliptical holes to emit the IR radiation at an angle from normal, and
change the voltage signal to selectively set the frequency range of the IR radiation.
