Image of FIG. 1.
FIG. 1.

The schematic of the hyperlens: many cylindrical shells are stacked to form a cylindrical ensemble.

FIG. 2.

Transmission character at the interface in Fig. 1. The circles represent the dispersion of electromagnetic wave in air, while the hyperbolic lines represent the dispersion of electromagnetic wave in hyperlens. The & arrow represents energy vector and wave vector of the source wave from air since these two vectors are in the same direction. The arrow describes the wave vector, while the arrow describes the energy direction of the transmitted wave at the interface between air and the material we defined. (a) The dispersion relation of Eq. (1) when , , and which is used in many existing designs. (b) The dispersion relation of the ideal case of electromagnetic wave in hyperlens when , , , and is very close to zero. (c) The dispersion relation of Eq. (1) when , , and which is used in our design. (d) The dispersion relation of the ideal case of electromagnetic wave in hyperlens when , , , and is very close to zero.

(a) -field distribution when the waves of two sources propagating through a hyperlens. The frequency of the TE wave is 3.97 GHz. The value of the inner radius of the hyperlens is 8 mm, while the outer one is 104 mm. The measurement trace (red dotted line) is 50 mm away from the outer radius of hyperlens. The value of the distance of the two sources is 7 mm, which is less than 1/10 of the vacuum wavelength. (b) -field distribution when the waves of two sources propagate through just air (without hyperlens case). All the geometric parameters are the same as the ones in (a).

(a) The schematic of the experimental setup. (b) The prototype of hyperlens in microwave band. The values of inner and outer radii of the prototype are 8 and 104 mm, respectively. (c) The unit of S-string structure. The geometric parameters of the unit of copper S-string structure are the same as in Ref. 8, , , , , and the size of substrate FR4 is with .
