When lights behind an obstacle are detoured and delivered to an observer, the observer can see a scenery behind the obstacle. Consequently, the obstacle becomes invisible. We have developed the theory of extremely broandband and low loss cloak medium design and demonstrated an invisibility cloak operation in the microwave frequency region.
If we can arbitrary transform the coordinate system around us, we will be able to fully control rays of light more than ever.
We are exploring possibilities of artificial compositions of extraordinary media that do not exist in nature by arranging fine subwavelength pieces of materials, such as silver or gold, mimicking natural atoms or molecules. These artificially composed media are referred to as metamaterials.
