Abstract: A unit cell can be used for a metasurface, metamaterial, or beamforming antenna. The unit cell includes a metal layer attached to a substrate. The metal layer defines an iris opening for the unit cell. One or more tunable capacitance devices are positioned within or across the iris opening. Each tunable capacitance device is to tune resonance frequency of the unit cell. Mass transfer technologies or self-assembly processes may be used to position the tunable capacitance devices.
