SCIENCE -BEND the LIGHT a panoply of new phenomena appear Researchers create bizarre optical phenomena, defying the laws of reflection and refraction

'The reflected beam can bounce backward instead of forward. You can create negative refraction. There is a new angle of total internal reflection
The frequency (color), amplitude (brightness), and polarization of the light can be controlled ; vortex beam (a helical, corkscrew-shaped stream of light) from a flat surface, next, lenses that could focus an image without aberrations'
