You can simulate materials, apply the wave equation, and get "layers" that compute outputs from given inputs, each modeled as points in space. It may be possible to manufacture such layers with metamaterials or something like that. https://www.science.org/doi/10.1126/sciadv.aay6946 https://www.science.org/doi/10.1126/sciadv.aay6946
