“…The broad transmission band at around 0.6 μm −1 is a typical LC resonance mode excited by the external electric field. We also find that the LC resonance frequency is insensitive to the change of the incident angles [18]. The blue dashed line shown between the two transmission dips approximately matches the transmission peaks indicating the predicted small linewidth SPP dispersion curve.…”

We propose a planar metamaterial design to realize active manipulation of plasmon-induced transparency. Under periodic boundary condition, a surface plasmon polaritons mode is excited by a plane wave with momentum conservation at oblique incidence. Due to the destructive interference between the surface plasmon polaritons mode and induction-capacitance resonance mode, an approximate 100% transparency window is produced at large incident angles. Simply by varying the incident angle, the plasmon-induced transparency features can be dynamically tuned. At the incident angle of 70°, a sharp transparency window with a bandwidth of 30 nm is obtained at 1.71 µm. The corresponding quality factor and group index are 58 and 410, respectively, which is promising for efficient plasmonic sensing, optical switching, and slow-light devices design.

“…Almost the same ring‐current strengths of 5.5 and 6.2 nA/T were obtained for the open and closed ring in Figure , respectively. The calculations suggest that construction of split‐ring resonators for frequencies of visible light is a challenge, because of the current leakage as the split‐ring resonator is thought to function as molecular capacitor–inductor (LC) circuit …”

A review of computational studies of magnetically induced current density susceptibilities in molecules and their relation to experiments is presented. The history of the investigation of magnetically induced current densities and ring currents in molecules is briefly covered. The theoretical development of relativistic and nonrelativistic computational approaches for computing current densities in closed-shell and open-shell molecules is discussed and different state of the art methods to interpret calculated current densities are reviewed. Numerical integration approaches to assess global, semilocal, and local aromatic properties of multiring molecules are presented and demonstrated on free-base trans-porphyrin. We show that numerical integration of the current density combined with guiding visualization techniques of the current flow is a powerful tool for studies of the aromatic character of complicated molecular structures such as annelated aromatic and antiaromatic rings. Representative applications are reported illustrating the importance of careful current density studies for organic and inorganic chemistry. The applications include calculations of current densities and current strengths for aromatic, antiaromatic, and nonaromatic molecules of different kind. Current densities in spherical, cylindrical, tetrahedral, toroidal, and Möbius-twisted molecules are discussed. The aromatic character, current pathways, and current strengths of porphyrins are briefly highlighted. Aromatic properties of inorganic molecules are assessed based on current density calculations. Current strengths as a noninvasive tool to determine strengths of hydrogen bonds are discussed.

We present a hybrid waveguide-magnetic resonance system with split ring resonators (SRRs) periodically arranged on top of a waveguide layer. Due to the destructive interference between the electric coupling to the magnetic resonance mode generated in the SRRs and the TE/TM waveguide modes supported by the waveguide layer, double plasmon-induced transparency is obtained at the infrared wavelength. Furthermore, the PIT resonance can be dynamically tuned by the incident angle. An ultranarrow PIT window with an FWHM of 7 nm is observed at the wavelength of 1.448 μm. The group index at the narrow PIT window can reach up to 100. We also demonstrate that the refractive index sensitivity and the figure of merit value can reach up to 640 nm/RIU and 64 in the sensing range, respectively. The proposed hybrid waveguide-magnetic resonance system with a high-quality factor PIT window is promising for efficient optical sensing, optical switching, and slow-light device design.
