    OAM-based reconfigurable doppler shifts enable PAPR reduction for multi-carrier doppler diversity by Zhao, Yufei, Ge, Yao, Yang, Zhaojie, Ju, Gaohua, Ma, Lu, Lu, Yilong, Guan, Yong Liang

    Published 2023
    “…In a recent study, we discovered that even when the transceivers are stationary, a specific spatial Doppler shift can be generated by rotating the wavefront structure of the OAM helical beams. Furthermore, arbitrary integer rotational OAM Doppler shifts can be realized flexibly by using the recently popular digital encoding metasurfaces. …”

    An artificial neural network model for multi-flexoelectric actuation of plates by Fan, Mu, Yu, Pengcheng, Xiao, Zhongmin

    Published 2023
    “…Flexoelectric effect can be used to design actuators to control engineering structures including beams, plates, and shells. Multiple flexoelectric actuators method has the advantage of less stress concentration and better control effect, but the mode-dependent optimal actuator locations could influence the flexoelectric actuation effect significantly. …”
