“…In practical applications, the requirements of a waveguide include a small size, a long transmission distance, and a small mode area. The main parameters used to evaluate waveguide characteristics include effective mode area, transmission length, figure of merit, and modal effective index [41,42]. The formulas for calculating each parameter are discussed in detail below.…”

In this paper, a long-range hybrid waveguide for subwavelength confinement based on double SPP coupling is proposed. The hybrid waveguide consists of a metal-based cylindrical hybrid waveguide and a silver nanowire. There are two coupling regions in the waveguide structure that enhance mode coupling. Strong mode coupling enables the waveguide to exhibit both a small effective mode area (0.01) and an extremely long transmission length (700 μm). The figure of merit (FOM) of the waveguide can be as high as 4000. In addition, the cross-sectional area of the waveguide is only 500 nm × 500 nm, allowing optical operation in the subwavelength range, which helps enhance the miniaturization of optoelectronic devices. The excellent characteristics of the hybrid waveguide make it have potential applications in photoelectric integrated systems.

“…Recently, spoof surface plasmon polaritons (SSPPs) were proposed to support the surface wave behaving alike the SPPs by using corrugated metallic structures at low frequencies. 5,6) Due to the characteristics of high-efficiency transmission, 7) lowpass, 8) and weak mutual coupling, 9) SSPPs have many applications in microwave filters, 10,11) sensing structure, 12) splitters, 13) and antenna 14,15) design. However, the components mentioned above are researched and designed based on the fundamental mode of SSPPs, which occupy large space due to the need for extra matching gradient transitions.…”

A compact dual-band and tri-band bandpass filters (BPFs) based on high-order modes of spoof surface plasmon polaritons (SSPPs) are proposed. By using meander line technique, the electrical size of the proposed SSPP structure reduced by 68% compared with the traditional rectangular-grating SSPP structure. The high-efficiency passbands are excited by high-order modes of SSPPs. Therefore, a dual-band and tri-band BPFs are designed by using two and three high-order modes of SSPPs, respectively. In addition, a notched band is obtained by loading three complementary split-ring resonators (CSRRs) on the bottom layer of the tri-band BPF. Thus, a quad-band BPF is achieved.
