Azopolymers exhibit fluidity originating from photoisomerization, enabling diverse structural control depending on the polarization state of the incident light. In this study, we developed a numerical analysis framework that couples OpenFOAM with the discrete dipole approximation to investigate the deformation behavior of azopolymer microstructures under circularly polarized plane-wave illumination. As a result, we demonstrate the possibility that, under counter-propagating circularly polarized light, angular-momentum transfer induces torsional deformation, leading to three-dimensionally chiral deformation accompanied by out-of-plane asymmetry.
