We report the conception, fabrication and characterization of a radar cross section reducing (RCSR) metasurface and its integration into a mesoscopic micromirror array for terahertz spatial light modulation (THz-SLM). The metasurface reduces the specular reflection of terahertz waves. Covering the metasurface with an electrically reconfigurable micromirror array enables the implementation of a micro-opto- electromechanical THZ-SLM with an average modulation contrast of 81% in the frequency range from 0.88 THz to 1.83 THz and a maximum contrast of 93% at 1.29 THz.
