Current fielded sensor protection is limited to fixed wavelength filters. Broadband filters designed to circumvent multi-wavelength laser threats are plagued by low transmittance, which degrades the sensitivity and performance of the sensor. Future warfighter threats include frequency agile lasers and thus have the potential of defeating fixed filters. Self-activating (passive) devices where prote ...

ABSTRACT: During Phase I, PaneraTech in partnership with UCLA-TANMS (NSF Center for Translational Applications of Nanoscale Multiferroic Systems) achieved a groundbreaking success by designing a multiferroic small antenna based on continuous spin rotation in ferromagnetic nanoelements in periodic electrode array patterns. Specifically, we developed Finite Elements Method (FEM) models to design nan ...

Successful completion of this Phase II proposal will fully characterize and evaluate a material for use in RF windows on hypersonic flight vehicles. Phase II will specifically examine the materials suitability through RF testing in X, Ku, and Ka bands and at elevated temperatures to 2000°F. The desired outcome will be a material with predictable, repeatable dielectric properties over frequency ...

To understand how insects and crustaceans sense and process light fields, researchers need a projection system that provides realistic wide field of view (FOV), high-speed imagery from UV to red (320-650nm) that includes polarization control. Insects and crustaceans have vastly different visual acuity and wavelength response from humans. In addition, some can sense polarization. Therefore, commerc ...

U.S. forces are benefiting from automation systems of unprecedented sophistication, empowered by advances in artificial intelligence (AI) and human-systems interaction. In air combat operations, onboard intelligent assistants monitor the aircraft, interpret and carry out commands, and report aircraft and system status, mission progress, threats and alerts. Because pilots and agents are part of a n ...

ABSTRACT: Researchers are identifying new biomarkers to help monitor, diagnose, and treat growing threats to the human body and enhance human performance. Recent sensor work combining biorecognition elements with field effect transistors (bio-FETs) has been shown sensitive and selective to biomarkers in the picomolar range with continuous detection; however device-to-device performance variability ...

The recent success of ultra-high speed direct digital synthesizers (DDS) provides excellent solutions to waveform generation directly at radar bands. An arbitrary waveform generators operating at clock frequency close to 52 Gs/s with bandwidth greater than 26 GHz and dynamic range close to 80 dB would greatly improve transmitter performance for applications such as telemetry and multi-purpose RF s ...

The objective of the proposed Phase-II effort by Spectral Energies LLC is to design and develop a fiber-coupled hyperspectral thermal LWIR imaging sensor suite to provide reliable, accurate 2D surface temperature measurements with high flexibility in practical gas turbine engines and propulsion systems. During the phase-II efforts, our team will work with fiber manufacture on custom designing of a ...

The overall goal of the proposed research program is to develop a ruggedized imaging system capable of visualization and analysis of the particle field and product gases in a multiphase blast. This will be accomplished by combining kHz-MHz-rate burst-mode laser technology with tomographic particle field velocimetry (PFV) and new nonlinear particle tracking methods to resolve dense particle fields. ...

Training can now be delivered on a large scale through emerging platforms, but training must be engaging to be effectively utilized. Key to providing training that makes a difference in the field is an understanding of how to induce high levels of engagement during learning and the ability to objectively assess engagement in real-time so that interventions can be tailored during training to optimi ...
