The nonreciprocal magnetoelectric (Tellegen) effect promises a multitude of exciting applications in connection to fundamental (e.g., axion electrodynamics) and applied physics (e.g., magnetless isolators). Notably, in the optical spectrum, there are no materials with noticeable and controllable magnetoelectric effects. In this talk, we will propose a three-dimensional metamaterial with an isotropic and resonant Tellegen response in the visible frequency range. The proposed metamaterial does not need external magnetization or temporal modulation and can be fabricated using readily available nanofabrication techniques and materials.
