In article number 1800081, Lei Zhou, Lin Chen, and co‐workers propose an alternative approach to realize high‐efficiency transmission‐mode metasurfaces to control electromagnetic wave‐fronts, based on hyperbolic metamaterial waveguides. An anomalous refracted beam is realized with a conversion efficiency of 42.9% in the microwave region and 77.9% in the near infrared region. This work may advance...
Metasurfaces have shown great potential to reshape the wavefront of electromagnetic (EM) waves, but transmissive meta‐devices face challenges of low‐efficiency and/or fabrication complexities. Here, an alternative approach to realize high‐efficiency transmission‐mode meta‐devices to control EM wavefronts, based on hyperbolic metamaterial (HMM) waveguides supporting tailored spoof surface plasmons...
