Airborne Sense-and-Avoid Radar for UAVs

Widespread use of unmanned aerial vehicles (UAVs) within the National Airspace System is limited because of regulatory restrictions on their access to shared airspace. The Airborne Sense and Avoid (ABSAA) Radar Panel, a phased array antenna developed by MIT Lincoln Laboratory, has the potential to facilitate the introduction of UAVs into the national airspace.

The Ins and Outs of Spaceflight Passive Components and Assemblies

RF and microwave components deployed in space flight applications can experience hundreds of degrees of temperature variation, massive amounts of radiation, and can be expected to operate at an elevated level for sometimes decades. The demands of operating in a space environment bring many unique challenges and unforgiving reliability requirements; therefore, designing passive components to meet these rigorous operation criteria necessitates a high level of design expertise, qualifications/certifications, and testing capability.

Next-Generation Fire Support Systems Boost Lethality

Soldiers view live-stream full-motion video from unmanned aerial vehicles via a smartphone. They access 3-D digital maps to send precision target coordinates. Soldiers are now relying on these advanced technologies to improve lethality and maintain battlefield dominance. These are among the improvements that will be embedded in future fire-support capabilities because the Army has started testing four upgraded systems for its Field Artillery units to provide more accurate and timely fire support to maneuver formations.

Introduction to Electromagnetic Compatibility

By definition, Electromagnetic Compatibility (EMC) describes the ability of a system, a piece of equipment, or some other electrical device that utilizes electromagnetic energy, to operate in its intended environment without suffering an unacceptable degradation in its performance, or negatively impacting the ability of another device to perform its intended function.

NRL Develops Novel Monolayer Ferroelectric Hybrid Structures

Scientists at the U.S. Naval Research Laboratory (NRL), Materials Science and Technology Division, have demonstrated that the intensity and spectral composition of the photoluminescence emitted from a single monolayer of tungsten disulphide (WS2) can be spatially controlled by the polarization domains in an adjacent film of the ferroelectric material lead zirconium titanate (PZT). These domains are written in the PZT using a conductive atomic force microscope, and the photoluminescence (PL) is measured in air at room temperature. Because the polarization domain wall width in a ferroelectric can be as low as 1-10 nm, this approach enables spatial modulation of PL intensity and the corresponding carrier populations with potential for nanoscale resolution.

Silicon Based Mid-Infrared SiGeSn Heterostructure Emitters and Detectors

Enhancing the performance of GeSn p-i-n photodiodes using gold metal nanostructures.

The goal of this research project was to advance the science and technology of silicon-based photonic devices using SiGeSn heterostructures. Such devices work in mid-IR spectral range and form the foundation for mid-IR photonics that enable on-chip systems for applications ranging from vibrational spectroscopy, chem/bio sensing, medical/health uses, to environmental monitoring. This project was mostly directed toward improving GeSn detectors with the use of surface plasmons induced by carefully designed metal nanostructures. The goal was to replace the current mid-IR detectors that are usually photodiodes made from narrow bandgap III-V or II-VI semiconductor compounds such as InGaAs, InSb, HgCdTe (MCT) or type-II In-GaAs/InGaSb superlattice. These photodiodes are incompatible with the CMOS process and cannot be easily integrated with Si electronics. The GeSn mid-IR detectors developed in this project are fully compatible with the CMOS process.
