The effect of Poisson's ratio to the reflector reshaping is investigatedthrough mechanical study of reconfigurable reflectors in this paper. The valueof Poisson's ratio corresponding to the minimum deforming stress is given andan auxetic lattice is proposed for the reflector surface. The parameters of theauxetic lattice are investigated for vary Poisson's ratio. A case ofreconfigurable reflector is studied, the curvature change and strain arecalculated by surface geometry analysis, and the negative Poisson's ratio isestablished for vary thickness. According to RMS calculation by the FEMstructure analysis, the thickness can finally be established.
