1. A radiating element comprising:
a plurality of higher order floquet mode scattering (HOFS) layers including at least a lowest layer unit cell, a middle layer unit cell, and a highest layer unit cell; and
a stripline feed layer comprising: a ground plane layer, one or more horizontal and vertical polarization stripline feeds, one or more horizontal and vertical polarization ground plane slots, and one or more ground vias, wherein the stripline feed layer creates an evanescent waveguide for resonance free stripline to radiating element coupling;
wherein the radiating element is aperture coupled with an active electronically scanned array (AESA) in a manner so as to enable the AESA to electronically steer a beam of radio waves to point in different directions without moving the AESA and radiate beams of radio waves at multiple frequencies simultaneously.
