Tailoring the electromagnetic responses of metamaterials: double negative medium designs and experiments

Summary form only given. Interest in double negative (DNG) media has arisen from many proposed microwave and optical applications, including novel imaging and propagation enhancements. The use of DNG media for ultra-small, efficient antenna applications has also been proposed. This microwave antenna application requires micron- and nanosized inclusions to realize a metamaterial that will exhibit the desired DNG properties. Several of the related physics and engineering issues will be reviewed.
