Meaning of supercollimation | Babel Free

Definitions

The focusing of radiation into a finite-width beam that shows very little diffraction.

Examples

“In photonic crystals, such thresholdless #92;mathcal#123;PT#125; transitions are shown to yield significant control over the band structure of the system, and can result in all-angle supercollimation, a #92;mathcal#123;PT#125;-superprism effect, and unidirectional behavior..”
