• Invisible Material: Researchers Model Metasurfaces in Hybrid Anapole Modes for the First Time

  Global trends are leaning towards miniaturization, minimalism, and portability – and that's the case for research, too. These days, metasurfaces are gaining popularity as platforms for super-thin devices equal, or sometimes superior to, their "normal-sized" counterparts. This is achieved thanks to “invisible” particles in anapole modes. Recently, these particles have revolutionized nanophotonics, but researchers from ITMO, Moscow, and Riga went even further and developed hybrid anapole modes. Their new model is more efficient than its predecessors and opens new applications for metasurfaces in optics.

• ITMO Scientists Enhance Multiphoton Processes in Perovskite Metasurfaces

  Researchers placed a polymer on a thin perovskite film and, using lithography, created a metasurface consisting of prolonged parallelepipeds. In the future, this will help create highly efficient visualizers for infrared radiation.
