In the past, the frequency spectrum ranging from 0.3 to 3THz (or 300 to 3000GHz) was spoken as infamous “Terahertz Gap” as it lies between traditional microwave and infrared domains but remained “untouchable” via either electronic or photonic means. The conventional “transit-time-limited” electronic devices can hardly operate even at its …

Cyber crimes and attacks continue to expand exponentially and involving more and more advanced and sophisticated techniques to infiltrate corporate networks and enterprise systems. Types of attacks include advanced malware, zero day attacks and advanced persistent threats. Flawed software, the root of most program errors and security vulnerabilities, is a critical …

During the past decade information technologies have driven the productivity gains essential to U.S. economic competitiveness, and computing systems now control significant elements of critical national infrastructure. As a result, tremendous resources are devoted to ensuring that programs are correct, especially at scale. Unfortunately, in spite of developers’ best efforts, …

Today, the lowest echelon members of the U.S. military deployed in remote overseas locations are unable to obtain on-demand satellite imagery in a timely and persistent manner for pre-mission planning. This is due to lack of satellite overflight opportunities, inability to receive direct satellite downlinks at the tactical level and …

US military is facing increasingly Anti-access /Area denial environment,  a set of overlapping military capabilities and operations designed to slow the deployment of U.S. forces to a region, reduce the tempo of those forces once there, and deny the freedom of action necessary to achieve military objectives . “A2/AD capabilities …

Cities have become the new battleground and Hybrid or Urban Warfare the greatest threat being waged by ISIS to Boko Haram to Hamas to Ukraine rebels. Urban warfare is the only way the Islamic State of Iraq and Greater Syria will be defeated. Urban environments negate many traditional U.S. military …

The growth of the internet-of-things (IoT) and network-connected composed systems (e.g., aircraft, critical-infrastructure, etc.) has led to unprecedented technical diversity in deployed systems. From consumer IoT devices developed with minimal built-in security, which are often co-opted by malware to launch large distributed denial of service (DDoS) attacks on internet infrastructure, …

Military spectrum requirements are also increasing exponentially as military operations increasingly rely on access to the wireless spectrum in order to assess the tactical environment and coordinate and execute their critical missions. The demand for more and timely information at every echelon is driving an increase in DoD’s need for …

After nearly a century of dominance as the material of choice for aircraft, metals are seeing increased competition from composite materials in use on Aircrafts. In the modern age, the aerospace industry is also looking ahead to tougher, lighter, and more heat-resistant materials that would lessen emissions, cut fuel costs, …

Brillouin scattering is an effect caused by the χ(3) nonlinearity of a medium, specifically by that part of the nonlinearity which is related to acoustic phonons. An incident photon can be converted into a scattered photon of slightly lower energy, usually propagating in the backward direction, and a phonon.   …
