※ Near-field distribution formed by random nanoislands was analyzed upon switching of incident light. It was shown that the behavior can be used for high-performance imaging and detection such as super-resolution microscopy.

※ The results titled“Metallic 3D random nanocomposite islands for near-field spatial light switching”will be published in Advanced Optical Materials, one of the top journals in optics (Q1 with IF 6.875).

※ This study was led by Taehwang Son and Gwiyeong Moon (co-first author) of the BPEL (Supervising Professor: Donghyun Kim), Yonsei University.
