ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

ABSTRACT:Modulator linearity and efficiency, in addition to bandwidth, are important parameters in characterizing a modulator. In general, improving modulation efficiency is highly desirable since higher modulation efficiency allows lower RF signal to impose equivalent change in the optical beam whereas improved linearity increases the dynamic range available to analog signals conveyed and process ...

ABSTRACT:Hyperspectral imaging is a technique used to simultaneously capture spatial and spectral information of an object scene, making it a valuable technique for applications in remote sensing and military battlefield environments. In the case of long wave infrared (LWIR) imaging, a hyperspectral approach offers an opportunity to improve upon the detection capabilities of standard broadband sen ...

ABSTRACT: Under the proposed effort, PSI will leverage a novel pmmW imaging technology developed under a prior Navy program to realize the low size, weight, and power sensors required for UAV implementation. This technology is based on an optical upconverted distributed aperture technology that can make use of the full aperture of the aircraft thereby maximizing achievable resolution. This sensor ...

ABSTRACT:In this phase II effort we will commercialize the high speed, high power, modified uni-traveling carrier (MUTC) photodiodes (PDs). To this end, we will develop reliable packaging solutions for discrete PDs, PD arrays, balanced PDs and waveguide based PDs. We will also transition the chip fabrication process for continuous, high volume supply of quality MUTC PD chips. In the first six mont ...

FPGAs have attracted a great deal of attention over the past decade because of their performance, scalability, and cost relative to traditional hardware platforms. However, one of the most significant disadvantages of FPGAs is based on the underlying architecture on which they are built. Specifically, routing delay through the chip is one of the largest bottlenecks in developing FPGA-based appli ...

A novel methodology is proposed for the integration of low volume fractions (~5% by vol) of high aspect ratio ferromagnetic nanomaterials into structural composite materials, to engineer electromagnetic properties in the microwave regime. The general approach is to disperse the nanomaterial (flake form) in a thermoplastic polymer that is selected to be the same as the toughening agent in the struc ...

Based on multiple technology platforms, innovative nanomaterials with much improved magnetodielectric properties have been developed in the Phase I program. Following Edison’s model of product and process development for technology innovations, Phase-II will pursue further incremental improvement in material properties upon the concept-proving material platforms to achieve high and matched die ...

Based on multiple technology platforms and theoretical analyses, in the Phase I program we have demonstrated the feasibility that RF polymers with desirable high frequency properties can be achieved. Following Edison¡¯s model of product and process development for technology innovations, Phase-II will pursue further incremental improvement in material properties upon the concept-proving materi ...
