Abstract
A microstructure to interact with electromagnetic waves by changing optical aspect in selected areas in response to an external signal, the microstructure comprising: a plurality of responsive elements, each responsive element capable of presenting at least two different optical aspects and changing between the optical aspects based on an applied external signal; and a support substrate containing the responsive elements, wherein at least a part of the support substrate defines an optical structure containing a plurality of assisting optical elements each optically enlarging an image from the responsive elements associated with the assisting optical element.
