Anisotropic Grid Generation
Abstract
During this program we have had several major accomplishments. These include finalizing our prior work on simple anisotropic surfaces consisting of discrete regions of homogeneous impedance values, and demonstrating them in the form of several useful structures. Examples include beam shifting structures, and scattering control surfaces. We have also developed a new method for patterning anisotropic surfaces based on defining a set of points which are shifted according to the desired impedance, and then used to define a lattice of cells. The goal of this work is to create smoothly varying inhomogeneous anisotropic impedance surfaces with arbitrary and well-defined impedance profiles that can perform useful functions. We have demonstrated this method in the form of a planar Luneburg lens, and an improved beam shifting structure. We have also developed a method for validating that the pattern of unit cells accurately reproduces the desired impedance function, although this last task is currently still in progress. Our next work is to develop a way to automatically define the starting function for the cell generation algorithm. At that point we will have a full procedure for starting with a desired impedance profile, and validating that the final output produces the intended profile.
