Abstract The growing prevalence of copyright products worldwide poses serious threats to economic security and human health.Developing advanced anti-counterfeiting materials with physical unclonable functions offers an attractive defense strategy.Here, we report multimodal, dynamic and unclonable anti-counterfeiting labels based on diamond micropar
A dielectric resonator antenna (DRA) with the loading of metasurface (MS) is proposed for low-profile, wide-bandwidth and compact-size.Firstly, an MS structure consisting of 6 × 6 periodic metallic patch cells is loaded above the DRA.It aims to excite an additional TM surface wave above the fundamental TE111 mode of the rectangular DRA.Then,
