摘要:

等离子体点火在各种科学和工业应用中至关重要,需要高效且稳健的执行机制。在这项工作中,我们通过结合对复频率平面中光散射基本方面的分析,提出了一种创新的等离子体点火方法。我们首次展示了高功率虚拟完美吸收(VPA)机制,这是一种在谐振器内完美捕获光的开创性方法。通过精心设计入射波的时间分布,我们有效地最小化了点火阶段的反射,从而显著提高了该过程的效率和韧性。通过全面的实验研究,我们验证了这种方法的可行性,确立了VPA作为无反射激发和等离子体放电最优控制的强大工具。通过解决传统等离子体点火方法的局限性,本研究代表了迈向等离子体技术变革性进步的关键一步,并对改善众多应用的性能和可持续性具有可喜意义。

英文摘要:

Plasma ignition is critical in various scientific and industrial applications, demanding an efficient and robust execution mechanism. In this work, we present an innovative approach to plasma ignition by incorporating the analysis of fundamental aspects of light scattering in the complex frequency plane. For the first time, we demonstrate the high-power virtual perfect absorption (VPA) regime, a groundbreaking method for perfectly capturing light within a resonator. By carefully designing the temporal profile of the incident wave, we effectively minimize reflections during the ignition stages, thereby significantly enhancing the efficiency and resilience of the process. Through comprehensive experimental investigations, we validate the viability of this approach, establishing VPA as a powerful tool for reflectionless excitation and optimal control of plasma discharge. By addressing the limitations of conventional plasma ignition methods, this research represents a pivotal step towards transformative advancements in plasma technology, with promising implications for improving the performance and sustainability of numerous applications.
