Concept illustration of waveform generations and beam shaping of various FMCWs by a programmable STCM with nonlinearly periodic phases. (IMAGE)
Caption
Under the control of field programmable gate array (FPGA) that offers external nonlinear periodic voltage control signals, the different types of FMCW signals can be synthesized as required at the same STCM platform. By further optimizing the initial voltage distributions among different regions of the metasurface, the propagation directions of the FMCW beams can be manipulated freely.
