Simultaneous excitation of electric and magnetic surface polaritons in a hyperbolic metasurface

【摘要】 Hyperbolic metasurfaces are powerful platforms for manipulating electromagnetic waves, yet conventional designs are limited to supporting either electric or magnetic surface polaritons. In this work, we design and experimentally demonstrate a hyperbolic metasurface that supports both polariton types within the same operational frequency band. By tuning the incident polarization, we selectively excite either electric or magnetic hyperbolic surface polaritons. This capability is confirmed through simulations and experiments, enabling polarization-adaptive control for advanced applications like multimodal sensing and reconfigurable wavefront shaping. Our findings pave the way for innovative devices in communication,imaging, and sensing.更多还原
