Solid State High-Power Microwave (SSHPM) system has demonstrated its effectiveness towards upsetting/disabling electronic components [1-4]. Although SSHPM systems are often much lighter and more compact than electron beam-based based HPM sources, such as klystrons, magnetrons, gyrotrons etc., SSHPM also generally produces less average power [1-4] but can generate comparable peak power which has been shown to produce various effects on targeted electronics. With support from the Ministry of Defence of Singapore, US Army Combat Capabilities Development Command (CCDC), and Air Force Research Laboratory/Directed Energy Directorate, Eureka Aerospace, Inc. has developed a novel multi-purpose compact and modular SSHPM system [5], hereafter known as the SSHPM Cannon. The main component of the SSHPM Cannon consists of an array of Integrated Blumlein Antenna (IBA) modules scalable to any size for the purpose of achieving the desired range and effects at targets [5]. The modular IBA architecture represents an integrated high power microwave source that operates in air, and in a variety of insulating media such as Flourinert to enhance holdoff voltage capabilities and without the need of an external antenna. The SSHPM Cannon can generate high-power electromagnetic pulses with peak power on the order of tens of gigawatts (GW), comparable to vacuum tube-based HPM source, and tuned in a variety of frequencies from VHF to L-band. Moreover, the thin shape of the SSHPM Cannon can potentially be conformed to any platform surface. The applications of the SSHPM Cannon consists of vehicle and boat stopping, as well as counter unmanned aircraft systems (cUAS). In addition, the system also has the potential capability to remotely neutralize ground surface and buried explosive hazards (EHs) for counter-IEDs missions. Results from the recent SSHPM Cannon prototype demonstration will be presented and discussed.
