ABSTRACT
Optical scanning microscopes of different types are one of the most
important elements of nanoplasmonics, nano-optics, and nanotech-
nology in general. Scanning near-field optical microscopes (SNOMs)
hold a significant place among these microscopes (nanoscopes)
(Pohl and Courjon, 1992; Dunn, 1999). Recently, optical scanning
microscopes were widely used even for the investigation of single
molecules (Betzig and Chichester, 1993; Trautman et al., 1994; Xie
and Dunn, 1994; Ambrose et al., 1994; Bian et al., 1995; Veerman
et al., 1999; Gersen et al., 2000, 2001; Hosaka and Saiki, 2001; Butter
and Hecht, 2006). Interpretation of these and other experiments
(Shubeita et al., 2002, 2003; Aigouy et al., 2003; Wenger et al.,
2005; Rigneault et al., 2005), in which a nanohole plays a crucial
role, is related to necessity of understanding of properties of optical
fields near nanoholes. On the other hand, in a case of an array of
nanoholes in a metal film, sometimes anomalous light transmission
through these holes arises (Genet and Ebbesen, 2007; Ebbesen
et al., 1998; Grupp et al., 1999; Degiron et al., 2004; Degiron and
Ebbesen, 2005; Wannemacher, 2001). Balykin et al., (2003, 2005)
proposeduse unique optical properties of optical fields in nanohole
arrays for control of atoms’ and molecules’ motion with nanoscale
accuracy.
