"High power microwave (HPM) sources have important potential application in a variety of military and non-military areas. One of the key stepping stones to reaching many of these applications is the development of a source capable of gigawatt level poweroutput in a microsecond long pulse at a reasonable repetition rate. In addition, it would be highly desirable if this source were reasonably com ...

"The integration of large-area MEMS devices with electronic circuitry promises to deliver significant benefits, such as reduction of device size, increased sensor sensitivities, and reduced fabrication costs. Further, the use of flexible substratesprovides additional benefits in improved environmental performance, conformability, and lower fabrication costs. The applications of an integrated lar ...

"The proliferation of weapons of mass destruction and the ballistic and cruise missiles that could deliver them pose a direct and immediate threat to the security of U.S. The capability to defend against an attacking missile in the boost, midcourse, anddescent phase increases the chances that the missile and its payload will be destroyed. Given the prominent heat signature of ballistic missiles, i ...

"Directed Energy and RF weapons methods for defending against cruise and ballistic missiles rely on spark gap-based systems. RF weapons rely on two parameters for effects against electronic systems; extremely high electric fields for range coveragehigh repetition rates for energy on-target heating of electronic components. High voltage pulse power systems are typically spark gap based sources t ...

"Missile defense systems rely on computational electromagnetic techniques to simulate potential missile threats. Simulation techniques for radar scenarios are rapidly increasing in their importance as budget restrictions reduce support for extensivedesign testing and flight data collection. These simulation techniques rely on advanced computational electromagnetic tools which typically require l ...

"Missile defense platforms will require a variety of electric weapons for a balanced attack defense. The integration of multiple electric weapons into a single vehicle platform requires very compact power systems and/or reconfigurable power systemsoptimize space and weight. For example, the same prime power source can be reconfigured to supply energy for vehicle propulsion and for hypervelocity e ...

"Kinetic Kill systems, such as Seeker missiles, rely on Continuous Wave (CW) microwave signals or Infrared (IR) technologies for tracking entry vehicles. These systems are coupled with a volume/range tradeoff and have not proven to be a reliable means oftracking missile threats. Common reasons include their susceptibility to countermeasures and their long processing time of information. Both sys ...

"Ballistic missile defense requires the ability to find, track and intercept a threat missile before it can reach its target. The kinetic kill vehicle (KKV) is a fundamental means to intercept and destroy the threat. To be successful, the KKV must be ableto acquire and track the target autonomously while steering itself on an intercept course. It must do this within a very small Circular Error ...

"Through theoretical analysis and experimental testing ASI is ascertaining the suitability of using gas plasma for a high-powered, reconfigurable antenna operating in both the S and X-bands of the electromagnetic spectrum. This design would be used todetect and track ballistic missile. We believe this design will allow development of multifunctional, multi-spectral plasma array antennas capable ...

"The performance of any radar, antenna, or electronic system depends on its ability to project and defend itself against various forms of electromagnetic interference including frequencies in the S and X band. Our proposal is to design a plasma barrier andtunable frequency selective surfaces that can be turned on and off on demand to shield antennas, radar, or electronic equipment. Metallic freque ...
