Achieving and maintaining effective control of our nation`s maritime borders which comprise 95,000 miles of shoreline and navigable waters, and 361 ports is an ongoing challenge. Due to greater numbers, increased maneuverability and reduced observables, smaller vessels pose unique and special… More

The multipactor effect is a major challenge that is encountered in a number of areas involving high-power radio frequency or microwave systems. Particle accelerator systems associated with high energy physics research are limited by radio frequency window breakdown largely due to multipaction. The… More

Satellite RF components suffer from an additional design limitation that does not concern their terrestrial counterparts: multipaction, an electron avalanche effect that can reduce performance or permanently damage devices under certain conditions. To avoid the onset of this effect, the traditional… More

ABSTRACT: Emerging Directed Energy weapon systems are particularly attractive to Combat Commanders due to their graduated effects, light-speed propagation, minimum collateral damage and deep magazines relative to kinetic weaponry. There are multiple efforts within the military which aim to… More

Diode pumped alkali lasers have the potential to provide the required high efficiency for a laser-based missile defense system. However, traditional anti-reflective coating materials are not resistant to the alkali vapor environments associated with such systems, contaminating and degrading rapidly… More

Because Critical Program Information (CPI) is often embedded in integrated circuits, adversaries must now attack at the die level. As a result, Focused Ion Beams (FIBs) have become a preferred tool for reverse engineering. FIBs can bypass or create circuit elements at the lowest levels; however,… More

ABSTRACT: Sheets, or"mats"of EMI protective materials have critical value for many systems of strategic importance for the Department of Defense (DoD). It is of great importance that all such materials that are integrated into fielded systems are fully capable of meeting shielding… More
