![]() Visible light sensing technique has been developed and generally applied in communication, imaging, and display fields. We hope that this manuscript is suitable for “ Optical Materials”. The presented concept will help to promote the fusion of optical and microwave systems and expand the application prospects in future new wireless communication systems and radar systems. Therefore, three color components in the incident light field can directly control the metasurface for various EM functions, establishing the flexible connection between light and microwave fields. ![]() ![]() We exhibit that the incident light of blue, green, and red components can be detected and transformed into the desired metasurface scattering patterns. Ī 1-bit programmable unit is designed to regulate the reflected phase response of the scattering fields using the field-programmable gate array (FPGA) hardware system.īy integrating four photodiode arrays on the metasurface, we achieve the active sensing on trichromatic colors and achieve the real-time response in the scattering field control.In this paper, we propose a trichromatic-color-sensing (TCS) metasurface with reprogrammable electromagnetic (EM) functions, to establish an intelligent joint between light sensing and EM manipulations. ![]()
