Metallic plates embedded between dielectric slabs and
perforated by rectangular arrays of subwavelength holes with a dense
periodicity in one of the directions support extraordinary transmission (ET)
phenomena, viz. strong peaks in the transmittance frequency dependence.
Stacks of such perforated plates support ET phenomena with propagation
along the stack axis that is characterized by the left handed behavior. The
incorporation of the dielectric materials and dense periodicity allows
significantly reducing the illuminated area of the perforated plate required
experimentally to observe the ET phenomena as compared to the areas
required in the case of free standing rectangular hole arrays. This facilitates
the experimental investigation of ET under excitation in the Fresnel zone of
Gaussian beams. [--]
