High-Power Microwave Metamaterials for Phased-Array, anti-HPM, and Pulse-Shaping Applications
Abstract
Final performance report of the Young Investigator Program (YIP) project titled "High-Power Microwave Metamaterials for Phased-Array, anti-HPM, and Pulse-Shaping Applications" is presented in this document. The research conducted in this project resulted in a number of unique devices for operation in high-power microwave systems. Specifically, for the very first time, high-power frequency selective surfaces capable of handling extremely high-power levels were introduced and experimentally demonstrated. Other major findings of this project include the introduction, development, and experimental demonstration of two new classes of ultra-wideband, true-time-delay, and high-power-cable microwave lenses suitable for operation in high-power phased-array antennas and electronic attack systems. Through the basic research conducted in this project, a better understanding of breakdown and plasma generation in high-power microwave periodic structures and metamaterials was achieved. This new understanding resulted in the development of new techniques for creating fast acting, distributed discharge limiters as well as periodic plasma layers. Finally, the use of metamaterials in high-power microwave amplifiers was investigated and a new concept for designing high-power, millimeter-wave traveling wave tubes was introduced and verified using computer-based simulations.
