摘要

Abstract

The nonreciprocal magnetoelectric effect in Tellegen materials enables exotic phenomena such as axion-modified electrodynamics and fosters the development of magnet-free nonreciprocal media. As the nonreciprocal counterpart to the well-known chiral electromagnetic response

it offers a parallel framework in which many concepts developed for chiral materials can be translated to Tellegen media

potentially unlocking new avenues for fundamental studies and applications. Although predicted over 75 years ago and observed in only a handful of natural materials with very low strength

the strong optical Tellegen effect has remained experimentally elusive. Here

we report the first experimental demonstration of a resonant optical diagonal Tellegen effect in a metasurface

showcasing a response that is 100 times greater than that of any known natural material. This optical metasurface

consisting of randomly distributed cobalt-silicon nanoscatterers with strong shape anisotropy

utilizes spontaneous magnetization to achieve a robust Tellegen effect without the need for an external magnetic field. In addition to the Tellegen response

the metasurface exhibits both gyroelectric and gyromagnetic effects

contributing to nonreciprocal cross-polarized light reflection. We introduce a technique to independently extract the amplitudes of these three effects using conventional magneto-optical single-side-illumination measurements. The observation of the resonant Tellegen effects in the optical frequency range may lead to the experimental observation of axionic electrodynamics and compact bias-free nonreciprocal optical devices.
