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.
Claims14
An apparatus, comprising:
- an artificially-magnetic structure positioned intermediate first and second spatial locations and operable to propagate electromagnetic waves in at least one frequency band from the first spatial location at least partially through the artificially-magnetic structure to a first remote location and from the second spatial location at least partially through the artificially-magnetic structure to a second remote location, the artificially-magnetic structure defining an electromagnetic distance between the first and second spatial locations for the at least one frequency band that is substantially greater than a physical distance between the first and second spatial locations.
