Abstract

High-power microwave (HPM) antenna, one of the key subsystems in the HPM system, is used for HPM radiation. Its performance is partly determined by the impulse responses of reflector materials under HPM. Therefore, it is essential to investigate the impulse response characteristics of reflector materials under HPM. Instead of the traditional waveguide cavity, this study was based on the double elliptical reflector system with an open boundary. By using this system, the impulse response of reflector materials was measured, and the response of reflector materials of multiple types under various environments with different electric field strengths and pulse widths was tested. In terms of breakdown, reflection efficiency, and pulse waveform, aluminum and carbon fiber test plates were affected by HPM and compared. Finally, the impulse response characteristics of carbon fiber test plates were summarized. The proposed method applied in this research is universal, matches the practical application environment, and can be extensively employed in the impulse response research and test of reflector materials.

测量反射器材料的高功率微波脉冲响应特性

高功率微波（HPM）天线是 HPM 系统的关键子系统之一，用于 HPM 辐射。其性能部分取决于高功率微波下反射材料的脉冲响应。因此，研究反射材料在 HPM 下的脉冲响应特性至关重要。本研究采用了具有开放边界的双椭圆反射器系统，而不是传统的波导腔。利用该系统测量了反射材料的脉冲响应，并测试了多种类型的反射材料在不同电场强度和脉冲宽度的各种环境下的响应。在击穿、反射效率和脉冲波形方面，铝和碳纤维测试板受到 HPM 的影响，并进行了比较。最后，总结了碳纤维测试板的脉冲响应特性。本研究提出的方法具有通用性，符合实际应用环境，可广泛应用于反射器材料的脉冲响应研究和测试。
