Systems and methods for designing, optimizing, patterning, forming, and manufacturing symphotic structures are described herein. A symphotic structure may be formed by identifying a continuous refractive index distribution calculated to convert each of a plurality of input reference waves to a corresponding plurality of output object waves. The continuous refractive index distribution can be modeled as a plurality of subwavelength voxels. The system can calculate a symphotic pattern as a three-dimensional array of discrete dipole values to functionally approximate the subwavelength voxels. A symphotic structure may be formed with a volumetric distribution of dipole structures. A dipole value, such as a dipole moment (direction and magnitude) of each dipole is selected for the volumetric distribution to convert a plurality of input reference waves to a target plurality of output object waves.

A lens design method is disclosed for designing a lens to reshape an actual far-field radiation pattern of a radiation source, such as a spiral antenna, to a preferred far-field radiation pattern. The method comprises:determining a preferred far-field radiation pattern of the radiation source;deriving a corresponding near-field radiation pattern from the preferred far-field radiation pattern;determining an actual near-field pattern of the radiation source;mapping an electric field and a magnetic field of the actual near-field radiation pattern to the derived near-field radiation pattern using a transfer relationship, the transfer relationship comprising material parameters which characterize the lens; and,determining the material parameters.

Examples disclosed herein relate to a reflectarray panel for near-field wireless communication coverage area and designing the reflectarray panel. The method includes one or more following steps, including, determining a near field coverage area of the reflectarray panel, calculating a tangential reflected field on a reflectarray surface of the reflectarray panel based at least on a feed location and initial geometric parameters of the reflectarray surface, determining radiation pattern specifications with an incident beam pointed toward a center of the near field coverage area, performing a near-field pattern synthesis algorithm on an initial phase distribution of the reflectarray panel, determining a synthesized phase distribution on the reflectarray surface from a result of performing the near-field pattern synthesis algorithm, adjusting one or more geometric parameters of each reflectarray cell of the reflectarray panel to produce the synthesized phase distribution, and/or determining dimensions of the reflectarray panel for manufacturing.

An artificial magnet conductor includes a dielectric medium, basic cells, each being formed on a side of a front surface of the dielectric medium, and including a conductive patch pattern and a conductive loop pattern formed with a predetermined gap with the conductive patch pattern, a frequency selective surface on which the basic cells are periodically arranged on the front surface of the dielectric medium, and a conductive layer formed on a side of a rear surface of the dielectric medium. A phase change from an incident wave to a reflected wave with respect to the dielectric medium is set as an addition value in which a first phase change in the gap is added to a second phase change between the basic cell of the dielectric medium and the conductive layer. A thickness of the dielectric medium is calculated using the addition value.
