Recent news from the scientific sector suggests the future possibility of making people and other objects invisible. This accomplishment would be useful, especially for military purposes, making soldiers or tanks or trucks on the field or even planes invisible.

The procedure involves bending light around three dimensional objects. In the past, it has been possible to cloak (bend light around) two dimensional, thin objects. With the new technology, larger objects can be made easier to hide from view.

The reason we can see objects now is that the objects tend to scatter the light which strikes them, causing some of the light to reflect back to the eye. This new cloaking concept is similar to water flowing around a rock in a moving stream. The light waves as well as radar waves tend to go around the object rather than reflecting it.

The materials used in this procedure are referred to as metamaterials and include Teflon, ceramic and fiber composite. These metamaterials mixtures are designed to bend the light around objects and not create shadows or create reflections.

This concept, in some ways, resembles stealth technology although it does more than reducing its ability to be traced by radar. It actually makes light go around objects so they cannot be seen at all.
