High-fidelity spherical cholesteric liquid crystal Bragg reflectors generating unclonable patterns for secure authentication
Monodisperse cholesteric liquid crystal microspheres exhibit spherically symmetric Bragg reflection, generating, via photonic cross communication, dynamically tuneable multi-coloured patterns. These patterns, uniquely defined by the particular sphere arrangement, could render cholesteric microsphere...
