Magnetless reflective gyrotropic spatial isolator metasurface [PDF]
New Journal of Physics, 2021 We present the concept of a magnetless reflective gyrotropic spatial isolator (RGSI) metasurface. This is a birefringent metasurface that reflects vertically polarized incident waves into a horizontally polarized waves, and absorbs horizontally polarized

Recent advances in metasurface design and quantum optics applications with machine learning, physics-informed neural networks, and topology optimization methods [PDF]
Light: Science & Applications, 2023 As a two-dimensional planar material with low depth profile, a metasurface can generate non-classical phase distributions for the transmitted and reflected electromagnetic waves at its interface. Thus, it offers more flexibility to control the wave front.
