Novel High Power Microwave System Designs using Non-linear Transmission Lines

Abstract

Increased global volatility motivates the development of devices for nonlethal deterrence.Directed energy devices can provide forceful persuasion at a distance for both civilian and militarypeacekeepers. Additionally, increasing occurrences of vehicular terrorism further drive thedevelopment of technology to stop vehicles from a distance before they can injure civilians ordestroy property. Militarily, disabling motorized attacks before contact with troops is critical forreducing casualties while keeping the attackers alive for future interrogation. Directed energytechnology can provide these capabilities, although system size often limits application in the field.Thus, developing compact high power microwave (HPM) devices could facilitate fieldingdevices for nonlethal defense with increased standoff range [1], [2] or for radar or weapons systemsfor aircraft or ships. This proposal will assess the design of novel nonlinear transmission linesNLTLs) by examining the impact of composites comprised of various combinations of dielectricand magnetic fillers and leveraging various NLTL geometries, such as tapering, which are used inconventional transmission lines for matching [3] and may increase efficiency and energy in the RFoutput as it relates to pulse width while also providing additional flexibility in design.
