The artificial material slab emulating the 60 nm silver layer at 2 GHz (a) contains one antenna (19 mm long by 9 mm wide) at its center. The grid unit cell size is 7.6 mm, the traces are 0.19 mm; the dielectric permittivity is 3.5. (b) The plane-wave-interrogated test set up is shown in (c). The slot antenna of figure (a) is placed at the center of the metal table in (c). The Gaussian poly-rod horn antennas are connected to two ports of a vector network analyzer (VNA).
