摘要： A method includes determining an operating frequency of an antenna at a component of the antenna. The method includes determining, at the component of the antenna, a filter node of a plurality of filter nodes to activate to tune the antenna to the operating frequency. The method includes transmitting power to the filter node, wherein the power is transmitted via a first optical fiber. The method also includes sending a signal from the component to a light source. The activation of the light source sends an optical signal to the filter node. The filter node adjusts a characteristic of a radiating element coupled to the filter node using the power responsive to the optical signal. Adjustment of the characteristic facilitates tuning the antenna to the operating frequency.

摘要： An antenna includes, at least, a metasurface structure assembly and a feed. The feed is coupled with the metasurface structure assembly and is operable to provide a first type of electromagnetic radiation with a first radiation property to the metasurface structure assembly. The metasurface structure assembly is operable to receive the first type of electromagnetic radiation from the feed and to convert the first type of electromagnetic radiation into a second type of electromagnetic radiation and then back to the first type of electromagnetic radiation with a second radiation property for radiation from the metasurface structure assembly. The first radiation property and the second radiation property are different.
