分析了用简单的绕射模型计算室内环境中人体对毫米波射频的阻挡的可行性。该模型建立了一组近似，并在文中进行了评估，以确定这种简化方法对人体堵塞情况的适用范围。本文所做的工作：(1)简要描述了使用刀口模型对隐蔽性进行建模的数学支持；(2)确定了可应用于数学模型实现的潜在简化，从而允许用简单的2D形状对3D几何人体进行建模；(3)描述了这种简化的人体模型的偏振对毫米波阻塞的影响。
This paper analyzes the feasibility of using a simple diffraction model to compute the blocking of the human body to millimeter wave radio frequencies in indoor environments. The model makes a set of approximations that are evaluated in the paper, to determine the applicability limits of such simplified approach to the human body blockage case. The work presented here: (1) describes briefly the mathematical support that is used to model the concealment using the Knife-Edge model, (2) identifies the potential simplifications applicable to the mathematical model implementation that allow a 3D geometric human body to be modelled with simple 2D shapes, (3) characterizes the polarization influence on the mm-wave blocking for such simplified human body models.
