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 nanostructured material of the metal insulator metal (MIM) grating with localized magnetic enhanced is designed by the inductor and capacitor (LC) circuit model. It's shown that the electromagnetic field can greatly be enhanced when the magnetically resonance is excited. The characteristics of the localized magnetic resonance are discussed. Furthermore, the LC circuit model can be easily used to design the MIM grating for localized magnetic resonance. The geometry parameters predicted by LC circuit model match well with the results simulated by rigorous coupled-wave analysis method.

    ABSTRACT: In this study, a dynamic chiral metamaterial (MTM) structure leading to an asymmetric electromagnetic (EM) wave transmission for linear polarization is presented. The structure is composed of square-shaped resonator with gaps on both sides of a dielectric substrate with a certain degree of rotation. The dynamic structure is adjustable via various parameters to fit any desired frequency ranges. Theoretical and experimental analysis of the proposed structure are conducted and given in detail. The suggested model can provide constant chirality over a certain frequency band and thus, it can be used to design myriad novel devices such as EM transmission and antireflection filters, and polarization rotators for desired frequency regimes.

    ABSTRACT: In this paper, negative permeability metamaterial medium is modeled using the split-ring resonator (SRR) structure and is fabricated for use in waveguides as filter. Starting from the basic resonant and magnetic plasma frequency equations, effects of the various structural parameters of the SRR on its performance are studied for the desired resonant frequency. After the optimization study of the SRR unit cell, an SRR array is modeled. Effects of the orientation of the rings and the array, and the position of the array are also studied for the best filter response. The optimization studies are carried out using the commercial solver, CST MWS. Finally, the SRR array consisting of 135 unit cells is fabricated on a conventional FR4 substrate using PCB printing technique. The SRR array is also fabricated on a non-conventional silicon substrate using UV-LIGA technique. Both the arrays are tested and the experimental results are compared with the simulation results.
