Abstract: An antenna 300 comprising a housing 310 with an internal cavity 315. The cavity 315 holds an adjustable amount of electrically conductive liquid, and a twin-conductor feedline 350 connects the antenna 300 to a receiving and/or transmitting device. The conductive liquid in the cavity 315 of the antenna housing 310 acts as a first element and receives/transmits signals from/to the first feedline conductor, whilst the second feedline conductor is attached to electrical ground 320.

Abstract: In some examples, a biasing structure for a unit cell of a meta-surface comprises a first illumination source to irradiate a first photovoltaic element, the first photovoltaic element so configured as to generate a biasing current to bias an active asymmetrically conducting device bridging a pair of electrically separated conductive patches defining a surface of the unit cell.
