It is shown that subdiffraction imaging devices cannot produce focusing of energy into three-dimensional spots of subdiffraction size. However, three-dimensional subdiffraction imaging is possible as a consequence of a matching/tunneling process. © 2006 American Institute of Physics.application/pdf3 p.engWave mechanicsStereoscopyFourier analysisGeneralized functionsOptical imagingLensesOptical devicesPhotonic crystal devicesinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1063/1.2397022
