Abstract
Apparatus, methods, and systems provide electromagnetic compression. In some approaches the electromagnetic compression is achieved with metamaterials. In some approaches the electromagnetic compression defines an electromagnetic distance between first and second locations substantially greater than a physical distance between the first and second locations, and the first and second locations may be occupied by first and second structures (such as antennas) having an inter-structure coupling (such as a near-field coupling) that is a function of the electromagnetic distance. In some approaches the electromagnetic compression reduces the spatial extent of an antenna near field.
