空间探测中用于太赫兹波调制的柔性可重构超材料制造与主动操控

For THz wave modulation with multi-parameters in a large bandwidth in the space exploration, a flexible and reconfigurable metamaterials whose spatial pattern can be manipulated is proposed: The subwavelength structure arrays composed of micro/nano architecture with high aspect ratio are fabricated on a reconfigurable surface composed of nanomaterials; the localization deformation of the reconfigurable surface and the posture of the micro/nano architecture can be coupling manipulated for the metamaterials reconfiguration. The modulation mechanism of the metamaterials reconfiguration will be investigated, to establish the designing guidelines of the metamaterials; an integrated manufacturing process for the reconfigurable surface, whose localization deformation can be remotely controlled, is proposed; a nanoimprint stretching method is proposed to prepare the high-aspect-ratio micro/nano architecture, whose posture can be precisely controlled by external stimuli. Thus, the proposed metamaterials, which can be reconfigurable by a multi-field coupling means, supply an alternative method for THz modulation, aiming at developing the manufacturing and manipulating technology of flexible and reconfigurable metamaterials.
