Lett. 103, 221904 (2013); 10.1063/1.4833817 Phase-compensated metasurface for a conformal microwave antennaMetamaterials are comprised of metallic structures with a strong response to incident electromagnetic radiation, like, for example, split ring resonators. The interaction of resonator ensembles with electromagnetic waves can be simulated with finite difference or finite elements algorithms, however, above a certain ensemble size simulations become inadmissibly time or memory consuming. Alternatively a circuit description of metamaterials, a well developed modelling tool at radio and microwave frequencies, allows to significantly increase the simulated ensemble size. This approach can be extended to the IR spectral range with an appropriate set of circuit element parameters accounting for physical effects such as electron inertia and finite conductivity. The model is verified by comparing the coupling coefficients with the ones obtained from the full wave numerical simulations, and used to optimize the nano-antenna design with improved radiation characteristics.

Inkjet-patterned porous split-ring resonator and its performance study on metamaterial application

“…Split-ring resonators (SRRs) have been proposed for metamaterial applications [1,2] with various designs including single [3,4] and multiple [5,6] perimeters of various shapes. One of the most interesting proposals is the realization of an invisibility cloak that uses metamaterials to control the propagation of light with three-dimensional (3D) SRR structures.…”
