supercollimation

English

super- +‎ collimation

supercollimation (plural supercollimations)

(physics) The focusing of radiation into a finite-width beam that shows very little diffraction.
- 2016, Alexander Cerjan, Aaswath Raman, Shanhui Fan, “Exceptional contours and band structure design in parity-time symmetric photonic crystals”, in arXiv‎:
  In photonic crystals, such thresholdless ${\\displaystyle {\\mathcal {PT}}}$ transitions are shown to yield significant control over the band structure of the system, and can result in all-angle supercollimation, a ${\\displaystyle {\\mathcal {PT}}}$ -superprism effect, and unidirectional behavior..
