Abstract

It is a well-acknowledged fact natural ferromagnetism is hard to find in optical spectrum. In this article, a metallic nanoantenna is reported which facilitates the achievement of artificial ferromagnetism at optical frequencies. The proposed nanoantenna consists of two rhombuses joined together by a square has been designed and analyzed for magnetic field enhancement using finite element method (FEM). The proposed design is aims at generating magnetic hot spot in the optical frequency range
