ABSTRACT: The objective of this project is to design and fabricate multi-signal in-situ ablation sensors based on an acoustic transducer system, thermal measurement system (i.e., either photonic technology or in-situ thermal sensors based on ultra small thermocouples), and fast inverse heat transfer algorithms. This project will use the following approaches: Utilize commercially available opt ...

ABSTRACT: Robust optical coatings are of great importance across a broad spectrum of applications. Hard, durable, stress-free coatings are needed and used in everything from ophthalmic polymers to infrared optics. One of the principal shortcomings of typical inorganic oxide, nitride, and sulfide coatings when applied to polymeric substrates is the large difference in the coefficient of thermal ...

ABSTRACT: The objective of this STTR Phase I proposal is to investigate the feasibility of a hybrid organic/inorganic gradient index anti-reflective (GRIN-AR) coating on both rigid and flexible substrates, based on the resonant infrared matrix assisted pulsed laser evaporation (RIR-MAPLE) process. The hybrid organic/inorganic material approach enables both optical index control, as well as mechan ...

ABSTRACT: The work proposed involves the design and prototype concept creation of a high-performance thermal energy storage device (TES) based on graphene/ultrathin graphite and organic phase change materials. To achieve these goals, the following specific tasks will be accomplished: 1. Fabrication and design: use of emerging fabrication processes to develop a sub-scale three-dimensional struc ...

ABSTRACT: In this program, we propose to develop a miniaturized Electromagnetic (EM) wave sensor based on defect engineered slotted photonic crystal waveguide (PCW) Mach Zehnder interferometer (MZI). EO polymers with large EO coefficient (r33>150pm/V) will be designed and synthesized to refill the slot PCW in order to take advantage of high field concentration in the narrow slots. Band engineered ...

ABSTRACT: In this program, Omega Optics, Inc., in collaboration with the University of Michigan Ann Arbor and the University of Texas at Austin, proposes low-cost, high-throughput roll-to-roll (R2R) printing of integrated photonic devices by using a high-rate R2R ink-jet printing system in conjunction with a high-rate R2R nanoimprint lithography (R2RNIL) system and demonstrate fabrication of pho ...

ABSTRACT: ADI and ASU propose to develop a novel methodology for blade peak stress prediction from limited strain gage/tip-timing measurements when multiple vibratory modes are present. The current protocol assumes that only one mode is present and only provides upper and lower bound estimates of the blade peak stress when multiple modes are important. It is proposed here to construct the blade m ...

ABSTRACT: The main objective of this project is to design metamaterial-based MEM phase shifters, and to enable their application in phased-array radar and communications systems. A compact, low-loss, low-power-consumption, and non-dispersive Ka-band 4-bit phase shifter is chosen as the demonstration vehicle. To determine the feasibility of the overall project, the objective during Phase I will be ...

ABSTRACT: In the future, numerous military database, documentation, and mission-critical information systems will be migrated to the clouds, due to cloud cost-efficiency and accessing flexibility. However, the cloud servers are generally untrusted either for data owners or users. In this proposal, A3IS (Attribute-based Algorithms for Assured Information Sharing) is proposed for dynamically and se ...

ABSTRACT: The scope of this effort is to study the technical feasibility of producing electronics for programmable matter that can generate high-voltage actuation signals; receive, store, and execute a program; harvest and store energy; and wirelessly communicate with other similar devices. The target power budget for the electronics is 10W, with a form-factor of 0.1 sqmm, with no dimension being ...
