FIG. 1.

(a) A schematic illustration of a one-dimensional periodic array of subwavelength slits perforated in an ultrathin metal film on a quartz wafer, where the thickness of the film is , the width of the slits is , and the period of the slit array is . Axis shows the propagation direction and polarization of the incident plane wave. (b) Scanning electron microscope image of its corresponding structure. (c) Free-space measurement setup.
