ABSTRACT We study both theoretically and experimentally the transmission properties of a lattice of split ring resonators (SRRs) for different electromagnetic (EM) field polarizations and propagation directions. We find unexpectedly that the incident electric field E couples to the magnetic resonance of the SRR when the EM waves propagate perpendicular to the SRR plane and the incident E is parallel to the gap-bearing sides of the SRR. This is manifested by a dip in the transmission spectrum. A simple analytic model is introduced to explain this interesting behavior. Comment: 4 pages, 4 figures

    ABSTRACT: The aim of near-field scanning optical microscopy (NSOM) is to reveal the distribution of the electromagnetic field around nanoscale objects. The full vectorial nature of this field is more difficult to measure than just its amplitude. It can only be fully reconstructed with exact knowledge of the optical properties of the probe. Here, we report and numerically explain that NSOM tips with a well-defined apex diameter selectively support azimuthally polarized light (|$E_{\text{azi}}$|$^2$/|$E_{\text{tot}}$|$^2$ $\approx$ 55$\,$% $\pm $ 5$\,$% for 1.4$\,$\mu m tip aperture diameter and \lambda$_0$ = 1550$\,$nm). We attribute the generation of azimuthal polarization in the metal-coated fiber tip to symmetry breaking in the bend and subsequent plasmonic mode filtering in the truncated conical taper.

    ABSTRACT: We study polarization-dependent transmission of light through arrays of single-slit split-ring resonator (SSRR) based systems at normal incidence using finite integration time domain (FITD) and finite element methods (FEM). It is found that a conventional planar array of SSRRs acts as an effective optical wave plate at certain polarizations of incident light. The effect is attributed to the intrinsic linear birefringence of individual SSRRs. A comparison is made with other split-ring resonator-based systems exhibiting wave-plate-like properties due to inter-SSRR coupling.

    ABSTRACT: Split ring resonator (SRR) structure can potentially be incorporated onto the truncated pyramidal microwave absorber. This study considers three different patterns of edge couple split ring resonator (EC-SRR) designs. Each EC-SRR design is then placed onto the truncated pyramidal microwave absorber. Outer split gap dimension widths of the EC-SRR are varied, and the various S21 performances are compared. This EC-SRR truncated pyramidal microwave absorber is simulated using CST Microwave Studio simulation software. The study and simulation are performed in low frequency range (0.01GHz to 1GHz) as well as in microwave frequencies range (1GHz to 20GHz). Simulation results of this EC-SRR show improvement of reflection loss and S11 performance in the high frequency range of the pyramidal truncated microwave absorber.
