A metasurface comprising:
- a dielectric material;
- a ground plane on a back side of the dielectric material;
- and
- at least one conductive element on a top surface of the dielectric material, wherein the at least one conductive element includes at least one of a ground-backed dipole or a slot array.

A method of designing a metasurface to reflect an electromagnetic (EM) wave, the method comprising:
- selecting, for the metasurface, an incident angle of an incident electromagnetic (EM) wave to be reflected;
- selecting, for the metasurface, a reflection angle of a reflected electromagnetic (EM) wave;
- and
- forming at least one reflective element on the metasurface, the metasurface further comprising a conductive element separated from a ground plane by an insulating substrate.

A metasurface, comprising:
- an insulating substrate;
- a ground plane against a first surface of the insulating substrate;
- and
- conducting elements on a second surface of the insulating substrate, wherein a first set of conducting elements in a first area is configured to reflect a first incident electromagnetic (EM) wave having a first incident angle at a first reflection angle, and a second set of conductive elements in a second area is configured to reflect a second incident EM wave having a second incident angle at a second reflection angle.
