欺骗表面等离子体激元 (SSPP) 具有高度受限的场限制和亚波长操作范围。然而，在低频区域，SSPP通常会受到场约束较差的影响，并且模式转换导致的损耗较大。折叠基底集成波导（FSIW）是基底集成波导的紧凑版本。然而，FSIW 的波导波长较大，因此对于紧凑型天线来说不是优选的。在这封信中，我们提出了 FSIW 和 SSPP 的结合，它兼具了 FSIW 和 SSPP 的优点。与纯SSPP相比，FSIW-SSPP由于其封闭结构，显着改善了低频区域的场限制和传输损耗。同时，由于SSPP的慢波特性，FSIW-SSPP将导波波长减少了67%。制造并测量了 FSIW-SSPP 原型。模拟和测量结果验证了预期性能。这种新结构在天线小型化方面具有潜在的应用前景。
Spoof surface plasmon polariton (SSPP) features highly confined field confinement and subwavelength operational scale. However, at the low-frequency region, SSPP usually suffers from a poorly confined field, and a relatively large loss resulted from the mode conversion. Folded substrate integrated waveguide (FSIW) is a compact version of substrate integrated waveguide. However, FSIW suffers from a large guided wavelength and hence is not preferred for compact antennas. In this letter, we propose a combination of FSIW and SSPP, which has the benefits of both FSIW and SSPP. Compared with the pure SSPP, FSIW–SSPP significantly improves the field confinement and transmission loss at the low-frequency region due to the closed structure. At the same time, FSIW–SSPP reduces the guided wavelength by 67% due to the slow-wave feature of SSPP. A prototype of FSIW–SSPP was fabricated and measured. The simulated and measured results validate the expected performance. This new structure has potential applications in the antenna miniaturization.
