Broad-Angle Multichannel Metagrating Diffusers
Yarden Yashno, Ariel Epstein
We present a semianalytical scheme for the design of broad-angle multichannel metagratings (MG), sparse periodic arrangements of loaded conducting strips (meta-atoms), embedded in…
Large-Period Multichannel Metagratings For Broad-Angle Absorption
Yarden Yashno, Ariel Epstein
We present an alternative scheme for obtaining effective power dissipation in planar composites, extending the recently proposed concept of metagrating (MGs), sparse arrangements o…
Metagrating-Assisted High-Directivity Sparse Antenna Arrays For Scanning Applications
Yaniv Kerzhner, Ariel Epstein
We present an analytical scheme for designing metagrating-enhanced sparse antenna arrays. Unlike previous work, the proposed method does not involve time-consuming cost function op…
Multimodal Anti-Reflective Coatings for Perfecting Anomalous Reflection from Arbitrary Periodic Structures
Sherman W. Marcus, Vinay K. Killamsetty, Ariel Epstein
Metasurfaces possess vast wave-manipulation capabilities, including reflection and refraction of a plane wave into non-standard directions. This requires meticulously-designed sub-…
