摘要: 为了深入分析能量选择防护结构(ESS)等周期结构作为天线罩时与天线产生的耦合效应，提高分析效率，该文提出一种基于坡印廷矢量法的耦合效应分析方法。该文从收发互易的角度，将天线当作发射器而非常规方法中的接收器对天线的电磁特性进行分析。从接收的角度理解，天线是一种从自由空间中捕获能量的装置，而能量分布可以通过坡印廷能流密度曲线来描述。同样地，能量选择防护结构对电磁波的扰动也可以通过能流密度曲线来描述。因此，天线、防护结构以及二者的耦合效应均可通过能流密度曲线进行研究和分析。结果表明，该文所提方法与常规分析方法具有良好的一致性。相比于常规分析方法，该文方法可同时对天线与防护结构的耦合效应进行可视化分析与量化评估，指导防护结构的尺寸、形状设计以及最佳安装位置，显著提高设计效率。Abstract: In order to analyze the coupling effect between periodic structures such as Energy Selection Structures (ESS) and antennas when ESS are used as radomes, and improve analysis efficiency, an analysis method based on Poynting vector methods is proposed in this paper. In the perspective of reciprocity between transmission and reception, the electromagnetic characteristics of antennas are analyzed as transmitters rather than receivers in conventional methods. From the perspective of reception, an antenna is regarded as a device that captures energy from free space. Therefore, the energy distribution can be described by the Poynting energy flow density curve. Similarly, the disturbance of electromagnetic waves caused by ESS can also be described by Poynting streamlines. Therefore, antennas, protective structures, and their coupling effects can be studied and analyzed through Poynting streamlines. The results indicate that the proposed method poses a good consistency with conventional analysis methods. Compared to conventional analysis methods, the proposed method in this paper can simultaneously visualize and quantitatively evaluate the coupling effect between antennas and ESS. The results can be used for the design of the size, shape, and optimal installation position of ESS, thus significantly improving design efficiency.
