“…The resonance that occurs when the wave vector of the incident light matches the wavelength of the plasma waves is called "SPR." Incident space waves at radio frequencies can induce surface plasmon waves propagating along the material interface through the use of gratings [45]- [47].…”

“…As a result, the transmission efficiency of the single aperture was significantly increased [21,22]. The incoming wave was coupled to these periodic grooves that were located around the aperture and a narrow beam at the output side could be generated [23][24][25][26][27]. Moreover, such a simple device illustrates broad technological implications.…”

“…We report these drastically improved transmission figures through a deep subwavelength aperture with an electrical effective area that is significantly smaller than the operational wavelength. Instead of employing electrically large covers or corrugations around the aperture [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]39] to facilitate the input signal coupling, our approach makes use of the magnetic resonance of the connected SRRs (CSRRs) that are integrated with an electrically miniaturized hole at microwave frequencies. In the following sections of the present paper, we aim to address both the theoretical and experimental analysis of the transmission enhancement mechanism that is maintained by the aid of two types of CSRR configurations.…”

Abstract:We report astonishingly high transmission enhancement factors through a subwavelength aperture at microwave frequencies by placing connected split ring resonators in the vicinity of the aperture. We carried out numerical simulations that are consistent with our experimental conclusions. We experimentally show higher than 70,000-fold extraordinary transmission through a deep subwavelength aperture with an electrical size of λ/31×λ/12 (width × length), in terms of the operational wavelength. We discuss the physical origins of the phenomenon. Our numerical results predict that even more improvements of the enhancement factors are attainable. Theoretically, the approach opens up the possibility for achieving very large enhancement factors by overcoming the physical limitations and thereby minimizes the dependence on the aperture geometries. ©2010 Optical Society of AmericaOCIS codes: (160.3918) Materials: Metamaterials; (050.1220) Diffraction and gratings: Aperture.

“…However, when the metal surface surrounding the subwavelength aperture is corrugated, the incident light can couple to surface waves that mimic SPs. Since the initial reporting of enhanced and directional beaming through subwavelength apertures, this phenomenon has been intensively researched in all its theoretical and experimental aspects [4,5,6,7,8,9,10]. All of this conducted research concerns the coupling of the transmission to the far field.…”

Abstract:We investigated the splitting of surface electromagnetic waves trapped at the output surface of a one-dimensional metallic grating structure. The output gratings of the structure asymmetrically such that the output surfaces at the different sides of the subwavelength aperture can support surface waves at different frequencies. The transmission amplitude as measured at the left side is 1,000 times of that at the right side at 16 GHz. At 24 GHz, the transmission measured at the right side is 20 times that of the left side of the structure. Therefore, surface waves are guided into the different sides of the aperture at different frequencies via metallic gratings. The experimental results are in agreement with the theoretical results.
