ABSTRACT: The proposed research will develop a method of compensating atmospheric disturbances in the transmitting subapertures of a phased array transceiver operating in the infrared. The aero-optical boundary layer and atmospheric turbulence create phase variations within each subaperture. To compensate these variations, an adaptive optical system will be used in each subaperture. The propos ...

ABSTRACT: Current and projected limitations on the maximum power from a high power single mode fiber laser amplifier impose architectural limitations on a high power phased array laser weapon system. Prior studies strongly indicate that when faced with this limitation the optimal approach is (to borrow the term for Paul McManamon) a Phased Array of Phased Arrays (PAPA) geometry wherein large(r) ...

ABSTRACT: Under the first phase of the program, Plasmonics Inc. and Sandia National Laboratories investigated a range of surfaces that yield non-Lambertian emission profiles in the thermal infrared. The second phase of this program will further maturate the designs developed in the first phase of the program. With the vast majority of the analytical work complete, focus in the second phase will b ...

ABSTRACT: The goal of this phase II proposal is to develop a commercial platform for printing high performance, single-walled carbon nanotube transistor circuits on large-area plastic substrate. Automated processes will be developed for the room temperature printing of metal, semiconductor, and dielectric materials with micron-scale alignment accuracy. The transistor performance will be enha ...

ABSTRACT: It is proposed to demonstrate a surface fabricated using thin film metamaterial designs that can exhibit rapidly varying angular as well as spectral emissivity profiles. The technology enables specification of desired angular pattern at design time, and can be fabricated in large area formats. BENEFIT: The proposed technology will allow directional control of thermal radiation in app ...

ABSTRACT: Optical refrigeration is currently the only demonstrated all-solid-state cryocooling technology. Optical cryocoolers are devices that use laser light to cool small crystal or glass cooling elements. The cooling element absorbs the laser light and reradiates it at higher energy, an example of anti-Stokes fluorescence. The difference between the energy of the outgoing and incoming light c ...

ABSTRACT: The emerging technology of protean glass/ceramic materials, where RF and DC electrical properties can be imbued in the material volume by laser excitation and subsequent material transformation processes has great potential especially for the military applications. In this Phase I research, Chemat has successfully prepared a protean glass which is photosensitive. A pattern such as a 3 ...

ABSTRACT: In this STTR effort a small business company Obalon LLC is teaming up with industry leader Aerospace Corporation for development of novel photostructural glass ceramic composition (PhotoCon) with capability of laser induced 3D conductor patterning inside the bulk material. The development fully utilizes available infrastructure and team's expertise for commercial glass ceramics pro ...

ABSTRACT: In this project, we assemble leading commercial and academic groups within nano-scale device simulation community to overcome the modeling bottleneck by implementing new high performance modeling methods for simulating the electrical properties of nano-scale devices. The majority of the tools will be integrated into an already existing and very user friendly commercial platform for simu ...
