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-…
Evidence for ultra long range energy transfer in organic photovoltaic donor-acceptor three dimensional films
Eran Avnon, Ariel Epstein, Olga Solomeshch +1
We report an ultra long range energy transfer in a layered donor:spacer:acceptor structures, which consist of the typical organic photovoltaic material system of P3HT as the donor…
Metagratings for Perfect Mode Conversion in Rectangular Waveguides: Theory and Experiment
Vinay Kumar Killamsetty, Ariel Epstein
We present a complete design scheme, from theoretical formulation to experimental validation, exploiting the versatility of metagratings (MGs) for designing a rectangular waveguide…
