Abstract

The long-metallic-strip (LMS) array proposed by J. B. Pendry has been widely studied in electromagnetic windows. However, it could only work for the single-band window, not the dual-band one, due to the plasma-like oscillation attenuating with increasing frequency. To solve the problem, we have analyzed the condition of EM windows and then proposed to introduce “parasitic” rings (PRs) into the LMS array. The design is called the LPR metasurface, which could open the dual-broadband window at large incident angles (60°–85°). In C band, the LPR metasurface could conserve the LMSs’ plasma-like oscillation, thus opening a broadband window for transverse-electric polarization. In K band, where the plasma-like oscillation has almost disappeared, the PR generates a capacitive resonance. It could open an additional window at large angles and provide a great out-of-band suppression concurrently. Unlike related studies, the PRs here are structurally easy and integrated into the LMSs. It has conserved the LMSs’ simplicity and continuity, thus could better meet processing and protective materials. Additionally, with the great performance at large angles, the LPR metasurface may find wide applications in hypersonic aircraft radars, 5G/6G base stations, and others.

带寄生环的长金属条阵列：一种大角度双宽带电磁窗的高效超表面

J. B. Pendry提出的长金属条（LMS）阵列在电磁窗口中得到了广泛的研究。然而，由于类等离子体振荡随频率的增加而衰减，它只能在单波段窗口工作，而不能在双波段窗口工作。为了解决这个问题，我们分析了EM窗口的条件，并提出了在LMS阵列中引入“寄生”环（PRs）的方法。该设计被称为LPR超表面，它可以在大入射角（60°-85°）下打开双宽带窗口。在C波段，LPR超表面可以保持lms的等离子体振荡，从而为横向电极化打开了一个宽带窗口。在K波段，类等离子体振荡几乎消失，PR产生电容共振。它可以在大角度上打开一个额外的窗口，同时提供很好的带外抑制。与相关研究不同的是，这里的pr结构简单，并集成到lms中。它保留了lms的简洁性和连续性，可以更好地满足加工和防护材料的要求。此外，凭借在大角度下的出色性能，LPR超表面可能在高超声速飞机雷达、5G/6G基站等方面得到广泛应用。
