Abstract

In this paper a design solution for creating the artificial magnetic response of nanostructured metamaterials in the optical frequency range is suggested. This design solution is a modification of the known effective rings formed by plasmonic nanospheres (located at the corners of a regular polygon). Instead of nanospheres we suggest to use bispheres (dimers) which allow us to provide a stronger robustness to Ohmic absorption in silver and, as a result, obtain the negative permeability at the edge between infrared and visible ranges. The study is presented in view of prospectives for isotropic magnetic and doubly negative metamaterials without strong spatial dispersion in the optical frequency range.
