✦ Synopsis

like a PMC surface for this direction of observation. It can also be noted that the fields are zero for Ο­ /2, except when Ο­ 0 and Ο­ . Thus, the field will propagate along the surface in the direction of the strips, that is, in the direction for which the surface behaves like a hard surface. This corresponds to localized surface waves following the strips, as investigated for strip loaded scatterers in [10]. The far field from a vertical dipole (z-directed) over the PEC/PMC strip surface is shown in Figure 4, where once again the anisotropic property of the surface can be noted. It can also be noted that the behavior of E and E when is close to /2 are almost interchanged compared to the case of the y-directed dipole.

We report on the construction of a scanning near-Ðeld optical microscope (SNOM), which has been designed to permit imaging at the solid/liquid interface. The probe consists of a tapered Ðbre tip and the so called lateral shear force is used for the tip-sample distance regulation. The liquid environm
