“…The transmission properties of SRR's and wires have been thoroughly studied [13,16,17,18,19,20,21,22]. The physical shapes of SRR's have expanded to include: double slit tetragonal resonators [23], microstrip resonators [23], single, double, and quad multigap split ring resonators [24,25], pairs of short wires [18], S shaped and omega shaped resonators [26], double bars [27], dog bones [28], and complementary structures [29]. The effect of SRR positioning and cavities vs. free space has been studied as well as intercavity systems [30].…”

“…Plasmonlike waves govern the main physics, even though the metals are perfect conductors at these wavelengths. Additionally, metamaterials with their subwavelength features already have a well-established background in the microwave regime [38]. Hence, Alu et al suggested covering the aperture with a metamaterial slab that would lead to improved transmission figures by minimizing the diffraction losses [39].…”

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.

“…This gives rise to a magnetic field which counteracts that of the incoming optical signal [5,6,7,8]. This results in a negative permeability which is a consequence of the magnetic resonance.…”

Fabrication of Large Area Fishnet Optical Metamaterial Structures Operational at Near-IR Wavelengths

et al. 2010

In this paper, we demonstrate a fabrication process for large area (2 mm × 2 mm) fishnet metamaterial structures for near IR wavelengths. This process involves: (a) defining a sacrificial Si template structure onto a quartz wafer using deep-UV lithography and a dry etching process (b) deposition of a stack of Au-SiO2-Au layers and (c) a ‘lift-off’ process which removes the sacrificial template structure to yield the fishnet structure. The fabrication steps in this process are compatible with today’s CMOS technology making it eminently well suited for batch fabrication. Also, depending on area of the exposure mask available for patterning the template structure, this fabrication process can potentially lead to optical metamaterials spanning across wafer-size areas.
