Abstract: Sparse metasurfaces are assembled from fewer meta-atoms while being able to outperform conventional metasurfaces. Sparse metasurfaces allow one to manipulate electromagnetic fields by accurately adjusting the response of each individual meta-atom according to a rigorous engineering procedure. The procedure involves solving inverse scattering problem and does not rely on heuristic generalized Snell’s law. The presentation started from fundamental theoretical aspects of sparse metasurfaces and arrived at a design procedure. The concept was validated by demonstrating performances of several experimental samples including conformal and reconfigurable designs.
