Abstract: There is provided an electromagnetic wave director comprising a substrate supporting a diffractive element formed from a two-dimensional array of subwavelength subcells deposited onto said substrate, said diffractive element operative to direct an electromagnetic wave signal generated by at least one electromagnetic wave transmitter to at least one electromagnetic receiver disposed within at least one coverage zone lying outside the line of sight of the transmitter, said diffractive element having metasurface prescription for modifying the amplitude and phase of incident electromagnetic wavefronts on each subwavelength subcell. There is also provided associated systems and methods.
