摘要
利用CST软件设计了一种基于锥形同轴过渡结构的电磁辐射腔,内外导体采用聚四氟乙烯介质进行支撑,在宽频信号源的激励下,电磁辐射腔内部产生任意频率TEM模式的电磁场,将细胞培养皿装置放于内外导体之间(电磁辐射区),从而实现对细胞的电磁辐射实验。通过理论分析与软件仿真,对电磁辐射腔的过渡结构进行优化,在DC-6GHz频率范围内,S11均在-10dB以下。
This paper presents the design of electromagnetic radiation cavity based on the taper coaxial line by u- sing CST software. The inner and outer conductor are supported by PTFE. The cavity is working at TEM mode excited by broadband signal source. Then in the experiment, cell culture dish can be placed between the inner and outer con- ductor. Optimizing the transition structure of electromagnetic padiation cavity by theoretical analysis and software simu- lation. As a result, S11 is under -10dB in the DC-6GHz frequency range.
