Modified Luneburg Lens Based on Metamaterials

Figure 4

Simulated electric field distributions for a point source embedded within the modified Luneburg lens at 10 GHz. (a) The lens has the ideal refraction index distributions as shown in 1. (b) The refractive index distributions of the lens are discretized. (c) Beam scanning for a point source moving along the circumferential direction.
