Advances in Pulsed Power Technologies

Dear Colleagues,

Pulsed power technology is one of the most promising and rapidly growing research areas in applied physics. Pulsed power technology involves multidisciplinary research covering energy, materials, environment, defense, plasma medicine, and agriculture. High-power electromagnetic pulse power sources can be used in fundamental research projects such as inertial thermonuclear fusion, the production of high-energy electron beams, high-power microwaves, excimer lasers, rays and neutron pulses. Pulsed power generators for gas discharge, water discharge, and electromagnetic field generation have promising applications in material surface treatment, waste purification, water treatment, food processing, and device sterilization.

The development of pulsed power technology focuses on two aspects. On the one hand, the search for methods to obtain record high pulse power and the development of devices to achieve higher pulse voltages and currents is a constant challenge in the field of pulsed power technology. On the other hand, the widespread use of pulsed power supplies in industry continues to provide new challenges and future development opportunities for pulsed power technology research in terms of pulse repetition frequency, average power, compactness, reliability and lifetime.

With this Special Issue, we would like to draw special attention to new ideas that can best support the technological advancement and application development of pulsed power. We welcome both traditional and non-traditional interdisciplinary solutions and also encourage the optimization of existing pulsed power technologies for enhancement and application expansion. This Issue is open, but not limited, to contributions in the following focus areas:

• High-peak power pulse generators;
• Spanning high-power broadband electromagnetic sources;
• Nanosecond pulse generators;
• High-power switching and high-repetition frequency switching technology;
• High electromagnetic energy density storage technology;
• Pulsed electrical insulation and breakdown;
• Explosive pulsed power techniques;
• Electromagnetic measurement techniques, intense particle beams and the associated diagnostics;
• Pulsed plasma applications in agriculture, food, health and biomedicine.
