Together with Kirill and colleagues, we designed and experimentally verified a set of resonant structures not only harness symmetry-protected bound states in the continuum, but also helical dichroism in response to different twisted light modes carrying orbital angular momentum. This nice concept was proposed by me and Kirill during an ANZCOP conference back to 2023, really nice to see the idea comes out as a solid scientific paper, now published in ACS Nano today!
