Abstract

A human-sized microwave invisibility cloak has been realized. The invisibility cloak uses fractal metamaterials with two cloaking layers to achieve a high fidelity re-attainment of the intensity of an unobstructed direct path over a better than 50% bandwidth. A human subject was cloaked demonstrating a new milestone in diverted imaging capabilities: electrically large; high fidelity; and broad bandwidth. Transformational optics must now be considered less limiting in the guidance of practical applications.
