“…It was also more than 35 times that of the LLSP mode in the SRSs. According to our previous semi-analytic theory [17][18][19], the imaginary part of the permeability element for the SW mode was smaller than that of the LW mode of TRSs and magnetic plasmon mode of DRSs. Therefore, the SW mode had a higher quality factor.…”

Abstract:We numerically investigated the magnetic plasmon resonances in double-rod and triple-rod structures (DRSs and TRSs, respectively) for sensing applications. According to the equivalent circuit model, one magnetic plasmon mode was induced in the DRS. Due to the hybridization effect, two magnetic plasmon modes were obtained in the TRS. Compared with the electric plasmon resonance in a single-rod structure (SRS), the electromagnetic fields near the DRS and TRS were much more localized in the dielectric surrounding the structures at the resonance wavelengths. This caused the magnetic plasmon resonance wavelengths to become very sensitive to refractive index changes in the environment medium. As a result, a large figure of merit that is much larger than the electric plasmon modes of SRS could be obtained in the magnetic plasmon modes of DRS and TRS. These magnetic plasmon mode properties enable the use of DRSs and TRSs as sensing elements with remarkable performance.

“…Because of bianisotropy CSRR and SRR can be excited for certain arrangements of the particles by s-or p-polarization respectively [10]). Otherwise we would be dealing with magnetic SPPs [14] which have been suggested to provide guiding below the diffraction limit [15], but are beyond the scope of this article.…”

Broadband spoof plasmons and subwavelength electromagnetic energy confinement on ultrathin metafilms

A complementary split ring resonator (CSRR)-based metallic layer is proposed as a route to mimic surface plasmon polaritons. A numerical analysis of the textured surface is carried out and compared to previous prominent topologies such as metal mesh, slit array, hole array, and Sievenpiper mushroom surfaces, which are studied as well from a transmission line perspective. These well-documented geometries suffer from a narrowband response, alongside, in most cases, metal thickness constraint (usually of the order of lambda/4) and non-subwavelength modal size as a result of the large dimensions of the unit cell (one dimensions is at least of the order of lambda/2). All of these limitations are overcome by the proposed CSRR-based surface. Besides, a planar waveguide is proposed as a proof of the potential of this CSRR-based metallic layer for spoof surface plasmon polariton guiding. Fundamental aspects aside, the structure under study is easy to manufacture by simple PCB techniques and it is expected to provide good performance within the frequency band from GHz to THz.

“…In 1999, Pendry et al proposed a nonmagnetic metallic element to achieve a strong resonant response to the magnetic component of the incident EM wave [1]. Since then, the magnetic resonance effect in metallic nanostructures has attracted considerable attention [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Coupling to the incident EM wave, these structures provide negative permeability.…”

A tri-rod structure (TRS), which can be seen as a combination of the double-rod structures reported by V. M. Shalaev et al. [Opt. Lett. 30, 3356 (2005)10.1364/OL.30.003356], is proposed to control the polarization state of an electromagnetic (EM) wave in the near-infrared range. When a plane EM wave propagates through the TRS system, two orthogonal hybrid magnetic eigenmodes are established as a result of the strong hybridization effect. Thus, linearly polarized infrared light is shown to change its polarization around the resonance range after passing through an array of TRSs. The wavelength dependence of the polarization state is also calculated, and various polarized waves can be obtained. A metamaterial made of a large number of TRSs could be utilized as a polarization controllable medium with possible applications in optical elements and devices.
