Sažetak
An idea of magnetic metamaterial particle at optical frequencies, based on a circular arrangement of plasmonic spheres has been proposed recently. Unfortunately, experimental verification of this interesting idea is very difficult and expensive due to current limitations of nanotechnology. On the other hand, there is also recently published approach with scaled experiments that make use of RF structures that behave similarly to plasmonic spheres but in the RF regime (‘ RF replicas’ ). Here we extend this approach to investigation of plasmonic magnetic particles. Numerical simulations clearly show that an appropriate arrangement of RF Best’ s spherical resonators supports circulating displacement current completely analog to circulating displacement current in related plasmonic arrangement at optical frequencies. In addition, an RF waveguide demonstrator analog to well known SRR-based subwavelength waveguide is numerically analysed. All obtained results show that should be indeed feasible to investigate electromagnetic properties of circular arrangement of plasmonic nanospheres by scaled experiments in RF regime.
