dc.description.abstractThis dissertation explores innovative advancements within the high-power electromagnetics (HPEM) domain, focusing on the optimization of electromagnetic sources, the development of compact and mechanically efficient systems, the rapid prototyping of advanced sensing techniques, and the conceptualization of effective protection methodologies. It adeptly bridges mechanical engineering and electromagnetics, enhancing conventional approaches and addressing existing challenges in the HPEM field. Key research methods span both computational and experimental modalities. First, a detailed stochastic analysis is conducted to optimize the design of Virtual Cathode Oscillators (Vircator), a type of HPEM source, with findings indicating a 30% increase in peak power output, accompanied by a minor frequency shift. A novel portable, cost-effective, and easily maintained switched oscillator (SWO) system is devised for susceptibility and vulnerability testing, employing mechanical integration and experimental validation. Furthermore, the dissertation employs additive manufacturing techniques to create a compact Luneburg lens, facilitating the design and validation of a portable direction-of-arrival estimation system. This innovative solution is not only more affordable than traditional counterparts, but its manufacturing process is streamlined and efficient. The research concludes with the prototyping of radar absorbing materials for stealth applications, utilizing intelligent rapid prototyping methodologies. This approach allows for enhanced production efficiency, thereby contributing to the field of protection techniques in HPEM. The implications of this thesis span the broad field of HPEM, encompassing electromagnetic sources, sensing, and protection techniques. The findings illuminate potential pathways for improving HPEM applications, integrating mechanical engineering insights, and emphasizing the importance of rapid prototyping methodologies.
