A new modified Equivalent Circuit Model (M-ECM) enabled Whale Optimization (WO) assisted electromagnetic (EM) approach is presented for an efficient design of a double square loop frequency selective surface (DSL-FSS) based conformal shielding structure. A simple single-layer DSL-FSS is designed, fabricated, and measured to suppress both wireless local area network (WLAN) bands without affecting the rest of the considered spectrum using ECM enabled WO. The analytical and measured results have been found in quite good congruence with each other. The measured transmission coefficient at 2.4 and 5.0 GHz shows suppression of 35 and 38 dB, respectively. Further, the angular stability, polarization insensitivity, and physical interpretation of the DSL-FSS shielding structure are investigated. Finally, the conformal behavior of the structure has been investigated for different bending radius and good agreement between simulated and measured results shows the effectiveness of the aforementioned technique for planar and conformal WLAN shielding applications.

ECM启用的鲸鱼优化为WLAN屏蔽应用提供了双频保形FSS的便捷设计

提出了一种新的经过改进的等效电路模型(M-ECM)的鲸鱼优化(WO)辅助电磁(EM)方法,用于基于双平方环频率选择表面(DSL-FSS)的共形屏蔽结构的高效设计。设计,制造和测量简单的单层DSL-FSS,以抑制两个无线局域网(WLAN)频段,而不会影响使用ECM启用的WO所考虑的其余频谱。已经发现分析和测量结果相互之间非常一致。在2.4 GHz和5.0 GHz处测得的传输系数分别显示出35 dB和38 dB的抑制。此外,研究了DSL-FSS屏蔽结构的角度稳定性,偏振不敏感度和物理解释。最后,
