In this paper we suggest and study a design solution of metamaterial made of raspberry-like clusters of silver triangular nanoprisms. We show that this design theoretically allows one to obtain isotropic negative effective permeability in the visible range even taking into account real dissipative losses in silver. To estimate the magnetic response of the structure two independent methods are used. The study is presented in view of prospective for isotropic doubly-negative metamaterials operating in the visible range.
