PRApplied Editors’ Suggestion

Our recent paper “Unveiling the Properties of Metagratings via a Detailed Analytical Model for Synthesis and Analysis” has just been published in Physical Review Applied, and was chosen as “Editors’ Suggestion”.
https://journals.aps.org/prapplied/abstract/10.1103/PhysRevApplied.8.054037
The paper explores the novel concept of metagratings, periodic arrays consisting of one or two subwavelength polarizable particles (meta-atoms) per period. Surprisingly, despite the utmost simplicity, these structures allow highly-efficient implementation of intricate beam-manipulating functionalities, such as perfect anomalous reflection. In our manuscript, we rigorously investigate metagratings based on capacitively loaded conduting wires for perfect wide-angle beam splitting, via a detailed analytical model. We show that based on this architecture, compatible with printed-circuit-board (PCB) manufacturing techniques, the synthesis can be completed almost completely analytically, prescribing the copper trace geometry required for reaching unitary coupling efficiencies.
Furthermore, the formulation allows analytical examination of the device susceptibility to conductor losses, fabrication imperfections, and frequency shifts. This examination reveals that metagratings feature distinct preferable working points, in which the sensitivity to these non-idealities is minor, directly realted to fundamental interference processes taking place within the device.
