【摘要】 针对研制的大功率微波(HPM)大气等离子体实验装置中一定封闭空间内微波准光学聚焦系统的空间辐射场强分布进行测试研究。由于需测量封闭有限空间内强电磁场的非均匀分布,直接采用HPM辐射场测试方法已不适用。利用研制的非金属传动装置,精确控制相对步进,采用各向同性场测试探头作为电场测试接收系统,通过量传完成小信号辐射场的非均匀分布测试。更多还原

【Abstract】 Radiation field distribution is tested within a certain confined space in microwave quasioptical focusing system of High Power Microwave(HPM) plasma experimental device. Because of the nonuniform distribution of strong electromagnetic fields in confined spaces, the traditional testing method of HPM radiation field is not applicable. Adopting non-metallic transmission device with the precise control on relative step, using the isotropic field test probe, the non-uniform distribution of the radiation field is tested. Accurate experimental data can be obtained for the study of HPM plasma with the test method.更多还原
