Shaping 3D Path of Electromagnetic Waves Using Gradient‐Refractive‐Index Metamaterials
An all‐dielectric semispherical lens with functions in shaping 3D wave‐propagation paths is proposed and experimentally verified. When radiation sources are placed in the central region, the lens behaves as a magnifying device to resolve the sources in subwavelength scale; while when the electromagn...
