Patent ID: 8837031

Claim:
A process of fabricating a finite-embedded transform structure for use as a transformation-optical/transformation-electromagnetic device comprising: computing a local finite spatial coordinate transformation of Maxwell's equations over a spatial region to be occupied by a transformation medium of predetermined electromagnetic functionality; determining a spatial coordinate metric for a non-transformational second medium or spatial region adjacent or surrounding the transformation medium; embedding the computed local finite spatial coordinate transformation into the determined spatial coordinate metric for the second medium or spatial region adjacent or surrounding the transformation medium, wherein the embedded transformation meets a topological condition that a metric of the transformation medium in a direction normal and parallel to an interface between the transformation medium and said second medium or spatial region is continuous at a boundary to said second medium or spatial region; and fabricating a finite-embedded transform structure comprising a transformation medium using a metamaterial capable of manipulating propagating electromagnetic fields based at least in part on the computed local finite-embedded coordinate transformation.
