Light Confinement By Subwavelength Objects In Near-Field Optics
We show that dielectric objects much smaller than the wavelength used to illuminate them, can produce a confined electric field that perfectly reproduces their shape. This field can be recorded by a scanning near-field optical microscope (SNOM), which explains how these devices reach a resolution far beyond the diffraction limit.
