Abstract:
A multilayer metalens includes a substrate having first, second, and third axes that are perpendicular to each other. A first layer of antennas is arranged, relative to the third axis, on the substrate. Each antenna of the first layer of antennas is rotated relative to the first and second axes based on a position of each antenna of the first layer of antennas along the first and second axes. A second layer of antennas is arranged, in the third axis, on the first layer of antennas. Each antenna of the second layer of antennas is rotated relative to the first and second axes based on a position of each antenna of the second layer of antennas along the first and second axes. Each antenna in the first and second layers of antennas has, in a plane parallel to a top of the substrate an elongated shape. Each antenna in the first layer of antennas has a different rotation relative to the first and second axes than an antenna in the second layer of antennas that is located, relative to the third axis, adjacent to the respective antenna in the first layer of antennas.
