Engineered light control materials, such as metamaterials, frequency selective surfaces (FSS) and nanoantenna fims are designed to transmit, absorb, reflect or re-radiate electromagnetic radiation, typically in the visible and infrared (IR) regions. In fact, nanoantennas combined with high-frequency THZ diodes are being developed to harvest thermal radiation and waste heat and convert it into electricity.

These structures typically incorporate combinations of metals, dielectrics and polymers in repetitive patterns in the micron to submicron size range. In order to interact with radiation effectively, large areas of these patterned materials are often required. Using our patented nanoforming technology, we have produced FSS nanoantenna films for IR signature control in greater than square-foot areas—some of the largest thin-film, flexible devices of this kind ever produced.
