Abstract
A stacked three-dimensional (3D) metasurface includes a first layer with a first kernel configured to apply a first convolution on a first frequency of an incident polarized light, and a second layer with a second kernel different than the first kernel. The second kernel is configured to apply a second convolution different than the first convolution on a second frequency of the incident polarized light and the second frequency is different than the first frequency such that the stack 3D metasurface provides at least two independent convolutions on the incident polarized light.
