Identifying and Isolating Signals Using Radio Frequency Photonics

A single antenna can be used for both transmission and reception. To accomplish this, the transmission must be isolated from the reception. In Figure 1, a radio frequency (RF) circulator is connected right after the antenna. The three-port device separates the transmit path from the receive path. After the circulator, a system can be used to identify the frequency of different signals. Once the frequency has been found, a filter with the right pass-band frequency can be used to isolate signals from each other.

Forward observers, experts in directing artillery and mortar fire onto enemy targets, have been testing a new piece of targeting equipment recently. “Black Falcon” soldiers of Headquarters and Headquarters Battery, 2nd Battalion, 319th Field Artillery Regiment, put their hands on the Joint Effects Targeting System (JETS) — a modular, man-portable, hand-held, day/night, all-weather, target observation, location, and designation system. Components of the JETS include a Handheld Target Location Module (HTLM); a Laser Marker Module (LMM); and a Precision Azimuth Vertical Angle Module, all mounted atop a tripod.

High Temperature Graphene-Peek Adhesive

Joining of composites can be a challenging issue. If adhesives are used, the joints are permanent and cannot be undone. If they need to be undone, inserts are often used and these inserts increase cost and weight. Additionally, fibers can be cut in the process leading to a part with weakened mechanical properties.

Bioinspired Surface Treatments for Improved Decontamination: Commercial Products

In January 2015, the Center for Bio/Molecular Science and Engineering at the Naval Research Laboratory (NRL) began an effort to evaluate and develop top-coat type treatments suitable for application to painted surfaces that would reduce retention of chemical threat agents following standard decontamination approaches. Four commercially available surface treatments were evaluated: NANOskin Hydro Express, Rust-Oleum® NeverWet®, Eagle One Superior NanoWax™, and Rust-Oleum® Wipe New.

Processing and Characterization of Lightweight Syntactic Materials

Conventional composite materials, in which a matrix material is reinforced by particulates, whiskers, and/or continuous fibers, have long been of interest as potential materials solutions to engineering needs. Typically, the benefits of these reinforcements are observed for cases of tensile loading, with only minimal improvement for cases of compressive loading. As a result, recent attention has grown in the use of hollow spheres as a potential reinforcement in metallic systems.
