Performing accurate simulations of large- and multi-scale electromagnetics problems has far-reaching implications in a variety of engineering and scientific disciplines. The same physics governs a diversity of applications including problems of importance for NAVAIR such as complex radome-antenna and antenna-platform interactions.  Such simulation problems involve complex materials, multiple feed ...

NP Photonics proposes to design and develop a compact and integrated radio frequency (RF) -to-optical transmitter at 1060 nm for balanced RF-over fiber photonic links by taking advantage of our mature single-frequency laser technology, multicore fiber fabrication technology, and substantial heterogeneous packaging experience and capability in fiber laser products. In this Phase I program, we will ...

We propose to develop a heterogeneously integrated optical transmitter for balanced radio-frequency (RF) photonic link applications on air platforms that incorporates a high-power Nd:Glass laser source operating near 1054nm. During Phase I, we will develop a Nd:Glass prototype laser using a design that has already been  used to demonstrate hundreds of mW of single-longitudinal mode (ultra-narrowb ...

SRICO proposes to develop a compact, high-performance, electromagnetic interference (EMI) and high-power microwave (HPM) resilient radio frequency photonic link for compact antenna remoting in US Navy submarine electronic warfare applications. EMI and HPM resilience are achieved by optically isolating the pick-up radio frequency (RF) antenna and optical transmitter from the photoreceiver. The opti ...

Effective hearing protection is essential for service members who work in hazardous noise environments and for whom permanent or even temporary hearing damage affects performance, endangers lives, and reduces quality of life. Various devices have been developed to attenuate high levels of impulse and continuous noise while allowing low-level sounds to pass through. However, issues with comfort, ea ...

A Quantum Cascade Laser's (QCL) core material is a series of nanometer scale layers of conduction band barrier and well materials designed to induce lasing electron energy levels. The key design feature of a QCL is the ability to repeat the laser core superlattice design to cascade electrons through the superlattice repetitions by repeated stimulated emission. Such designs are generally carefully ...

Current Zumwalt Class destroyers (DDG 1000) sea chest openings are unique because they must be flush to the hull, limiting implementation of common sea chest designs (e.g., bubble shields or raised inlets). This design results in the ingestion of higher amounts of ice, debris, and air, resulting in increased maintenance costs, potential pump failure, and degraded overall cooling performance. The N ...

Additive manufacturing (AM) is a rapidly evolving technology that is being used in a growing number of new and different applications. As applications become more diverse, so will the environments within which AM equipment is relied upon to operate effectively and produce high quality parts. One specific challenge is maintaining part quality when AM equipment is required to operate in environments ...

The Kairos Research Team, together with our partners at the University of Arkansas at Little Rock (UALR), proposes to develop an intuitive web-based Twitter Follower / Friend Assessment (TWIFFA) tool and associated app that can identify bots and bot-assisted accounts within a user’s network of followers and friends. TWIFFA will enable a user to input their Twitter credentials, scan followers and ...

For decades gas turbines have been a reliable source of propulsion for a variety of marine-based vehicles. Since their adoption as the go-to solution for vehicles requiring a higher power density than conventions diesel engines can produce, they have suffered from corrosion of their alloyed components. Long believed to be the primary source of the corrosion, great efforts have been made to reduce ...
