Figure 8

Slot antenna in two-layer grid: perspective view (a) and top view (b). Transmission through the array of such antenna (simulated) and transmission through the artificial slab (measured) show the extraordinary transmission phenomenon (c). Computed results of the field concentration at the open feed of the antenna (d) and the transmission of the resonance from the top surface to the bottom surface are seen in the E-field normal to the surface (e) and the principal transverse E-field (f).
