Fourier Convolution Operation on Metasurface-Based Hologram in Microwave Region
In this paper, a 0.1λ<sub>0</sub>-thick 1-bit coding metasurface is proposed to achieve a polarization-insensitive hologram under oblique incidence, utilizing compact ground-backed patch unit cells. Fourier convolution theory in a digital signal processing system is added to the hologram...
