这项工作旨在通过模拟基于反射阵列的毫米波筛选系统进行表征和验证，以用于安全应用。该系统能够重建整个人体的表面，并且可以使用单频检测衣服下隐藏的物体。引入创新的物理光学（PO）相关技术，计算模拟完整逼真的人体三维模型，同时具有精度和计算效率。此外，模拟位于人体模型表面的任意介电和金属结构用于评估反射阵列探测隐藏物体的能力。
This work is aimed at the characterization and validation through simulations of a reflect-array based mm-wave screening system for security applications. This system is able to reconstruct the surface of the whole human body, and it can detect concealed objects under clothing using a single frequency. Innovative physical-optics (PO) related techniques are introduced to computationally simulate complete realistic 3D models of human bodies with both accuracy and computational efficiency. Additionally, simulations of arbitrary dielectric and metallic structures located on the surface of a human model are used to assess the ability of the reflect-array to detect concealled objects.
