noosphere

we are too close
to the end of these sad bad times
to stop moving


what lives here:
microfiction, science, philosophy(?)
poetry, autobiography, photography
a bit of maths, art, music
and stuff

A paper published in the March 2009 issue of Society of Industrial and Applied Mathematics Review, presents an overview of the theoretical developments in cloaking from a mathematical perspective. One method involves light waves bending around a region or object and emerging on the other side as if the waves had passed through empty space, creating an “invisible” region which is cloaked. For this to happen, however, the object or region has to be concealed using a cloaking device, which must be undetectable to electromagnetic waves. Manmade devices called metamaterials use structures having cellular architectures designed to create combinations of material parameters not available in nature.
