Application of a metasurface lens

A metasurface lens comprising:

• at least one lamina configured to pass electromagnetic waves traveling along a radiating path that extends along an axial direction of at least one radiating structure, the at least one lamina including:
• a first surface spaced apart from a second surface in a direction parallel to the axial direction to define a lamina thickness;
• an axial region extending radially from a center axis of the at least one lamina and configured to align with the radiating structure along the axial direction;
• and
• a plurality of conductive scattering elements arranged on one or both of the first surface and the second surface,
• wherein an aperture extends through the axial region of the lens, the aperture comprising an area without any conductive scattering elements where the material of the at least one lamina is omitted, and
• wherein the radiating structure is exposed through the aperture.

A method of manufacturing an antenna comprising:

• positioning a lens of the antenna in a radiating path that extends in an axial direction, wherein at least one radiating structure of the antenna is configured to radiate electromagnetic waves along the radiating path, and wherein the lens is configured to pass the electromagnetic waves therethrough, the lens including:
• at least one lamina having a first surface, a second surface, a center axis that is aligned with the axial direction, a lamina thickness between the first surface and the second surface in a direction parallel to the axial direction, and an axial region extending about the center axis;
• and
• a plurality of conductive scattering elements arranged on the first surface, the second surface or both the first surface and the second surface,
• wherein an aperture extends through the axial region, the aperture comprising an area without any conductive scattering elements where the material of the at least one lamina is omitted, and
• wherein the at least one radiating structure is exposed through the aperture.
