Abstract
Articles to control an electromagnetic (EM) radiation in the range of 1 GHz to 100 GHz, and methods of making and using the same are provided. An EM controlling sheet structure includes a dielectric carrier layer and an array of metallic resonant elements supported by the dielectric carrier layer to form an EM metamaterial structure in a non-random pattern. The metallic resonant elements are oriented such that each metallic resonant element has an axis substantially parallel to each other and substantially parallel to a major plane of the dielectric carrier layer.

A method of making a sheet structure to control an electromagnetic (EM) radiation in the range of 1 GHz to 100 GHz, the method comprising:
- providing a transfer tool including an array of pockets on a major surface thereof;
- disposing a plurality of metallic resonant elements in the array of pockets of the transfer tool;
- contacting an adhesive surface of a dielectric carrier layer to the plurality of metallic resonant elements in the array of pockets on the major surface of the transfer tool;
- and
- removing the dielectric carrier layer along with the plurality of metallic resonant elements from the major surface of the transfer tool,
- wherein the plurality of metallic resonant elements is disposed on the dielectric carrier layer in a non-random pattern, and the plurality of metallic resonant elements is oriented such that each metallic resonant element has an axis substantially parallel to each other and substantially parallel to a major plane of the dielectric carrier layer.
