摘要

The theoretical tools of optical transformation and conformal mapping have enabled the transference of the concept of invisibility from the realms of mythology to scientific reality. A number of attempts have been made to achieve invisibility which relied on Nano or micro fabricated artificial composite material with spatially varying electro-magnetic properties. This approach limits the size of the invisibility region to a few wavelengths and is also very costly. Here, we experimentally solve this problem by designing a structure with low cost materials and simple manufacturing techniques based on the principles of refraction and lateral shift. This cloak developed is able to conceal macroscopic object of sizes of at least 3 orders of magnitude larger than the wavelength of light in all three dimensions. This clock can find huge application in defense and transformation optics.
