FIG. 1.

Geometry of a 2D waveguide structure with a ZIM material (region 1). An object (region 2) can be placed in the ZIM material.

FIG. 2.

(a) Transmission coefficients as a function of the normalized frequency. S1: The ZIM region embedded with the circular PEC barrier; C1: the circular PEC barrier replaced by the ZIM material; C2: the ZIM in the region (1) replaced by air. The inset shows the geometry of the S1 case. (b) The resulting electric field and magnetic fields distribution for the S1 case at .

FIG. 3.

The electric field (surface plot) and magnetic field (arrow plot) distribution produced by a point source driven at external to the matched ZIM slab. (a) The ZIM region embedded with a tiny PEC barrier; (b) the tiny PEC barrier replaced by the ZIM material.

Image of FIG. 4.
FIG. 4.

(a) Transmission coefficients as a function of the normalized frequency. S2: The ZIM region including the concealed object; C3: the ZIM in the region (1) replaced by air. The inset shows the geometry of the ZIM cloak concealing a “diamond.” (b) The resulting electric field and magnetic fields distribution for the S2 case at .
