WebMetasurfaces made of linearly birefringent meta-atoms such as rectangular nano-posts are commonly used to control phase and polarization, but a single layer of these meta-atoms cannot implement... Web19 gen 2024 · Optimization-based design techniques that rely on full-wave simulations mitigate this problem but thus far have been mostly applied to topology optimization of small metasurfaces. Here, we describe an adjoint-optimization-based design technique that uses parametrized meta-atoms.
