    Abstract: Systems and methods in accordance with embodiments of the invention implement electrically tunable metasurfaces. In one embodiment, an electrically tunable metasurface reflectarray includes: a mirrored surface; a conductive layer; a dielectric layer; where the conductive layer and the dielectric layer are in direct contact, and thereby define a conductor-dielectric interface; a plurality of subwavelength antenna elements; and an electrical power source configured to establish a potential difference between at least one subwavelength antenna element and the mirrored surface; where a potential difference between a subwavelength antenna element and the mirrored surface applies an electric field to a corresponding region of the electrically tunable metasurface reflectarray; where any applied electric fields in conjunction with the geometry and the material composition of each of the subwavelength antenna elements, the conductive layer, and the dielectric layer, enable the electrically tunable metasurface reflectarray to measurably augment the propagation characteristics of incident electromagnetic waves.

    Abstract: A space-based solar power station, a power generating satellite module and/or a method for collecting solar radiation and transmitting power generated using electrical current produced therefrom, and/or compactible structures and deployment mechanisms used to form and deploy such satellite modules and power generation tiles associated therewith are provided. Each satellite module and/or power generation tile may be formed of a compactable structure and deployment mechanism capable of reducing the payload area required to deliver the satellite module to an orbital formation within the space-based solar power station and reliably deploy it once in orbit.

    Abstract: Nanoparticles may be formed into colloidal crystals that are chemically linked to a substrate. In certain implementations, the nanoparticles are formed into a colloidal crystal on an initial substrate, and then brought into contact with a binding precursor capable of chemically linking the colloidal crystal to a final substrate. Reacting the binding precursor to chemically link the colloidal crystal to the final substrate chemically links the colloidal crystal to the final substrate via functional groups linked to the nanoparticles and the final substrate respectively.
