Mapping electromagnetic fields near a subwavelength hole

Permyakov, D.V.; Mukhin, Ivan S; Shishkin, I I; Samusev, Anton; Belov, Pavel A; Kivshar, Yuri


We study, both experimentally and theoretically, the scattering of electromagnetic waves by a subwavelength hole fabricated in a thin metallic film. We employ the scanning near-field optical microscopy in order to reconstruct experimentally the full three-dimensional structure of the electromagnetic fields in the vicinity of the hole. We observe an interference of all excited waves with an incident laser beam which allows us to gain the information about the wave phases. Along with the...[Show more]
