Full-wave EM simulation of human body blockage by dense 2D antenna arrays

This dataset, created using FEKO software, serves to investigate the impact of human body blockage on electromagnetic (EM) fields as observed by receiver antennas arranged in dense 2D/3D arrays. The simulation scenario involves an Hertzian dipole emitting radiation at 2.4868 GHz and positioned at a height of 0.99 meters. Field measurements are taken over a 3D array with multiple 2D arrays at varying distances from the source. An anthropomorphic obstacle representing a human body is included, featuring dimensions and material properties based on muscle composition. Simulations are conducted with the body at different positions and orientations relative to source and receivers considering real and imaginary part of EM field samples. The scenario includes no additional obstacles.

For a 2D array at x=4m, simulations consider three body positions: (1) x=2m, y=0m, (2) x=2m, y=0.25m, and (3) x=2m, y=0.50m. Further simulations mimic micro-movements like translations along x and y axes by ±λ/4 increments and rotations at each position by angles 0°, 45°, 90°, and 135°, aiming to replicate real-life motions. In total, we simulate 3 positions, and for each of them, we consider 9 micro-positions (0 or ±λ/4 increments along x and/or y around the main position - the one with both increments equal to zero -) with 4 rotations for each. Therefore, there are a total of 3x9x4 simulations.

The entire scenario involves 3D layouts of receiver arrays, with 50 surfaces composed of 90x180 elements spaced by λ/10.

本数据集基于FEKO软件构建，旨在探究人体遮挡对密集二维/三维阵列接收机天线所观测到的电磁场（Electromagnetic, EM）的影响。仿真场景中设置了一个工作于2.4868 GHz的赫兹电偶极子辐射源，其架设高度为0.99米。场域测量通过一套三维阵列完成，该阵列包含多组距辐射源距离各异的二维子阵列。仿真场景中包含一具基于人体肌肉组织参数构建的拟人化人体障碍物，其尺寸与材料属性均符合肌肉组织特性。本次仿真会调整人体障碍物相对于辐射源与接收机的位置与朝向，并采集电磁场样本的实部与虚部数据，且本场景未设置任何额外障碍物。

针对x=4m处的二维阵列，本次仿真共设置了三个人体障碍物主位置：(1) x=2m, y=0m；(2) x=2m, y=0.25m；(3) x=2m, y=0.50m。此外，仿真还模拟了各类微运动：包括沿x、y轴以±λ/4为步长的平移，以及在每个主位置上分别以0°、45°、90°、135°进行的旋转，以此还原真实人体的运动场景。总体而言，本次仿真共设置3个主位置，每个主位置下包含9个微位置（以主位置为基准，沿x、y轴以±λ/4为步长进行平移，其中步长均为0的位置即为主位置本身），且每个微位置对应4种旋转角度。因此本次仿真总共有3×9×4组仿真工况。

完整的仿真场景包含接收机阵列的三维布局，该阵列由50个阵面组成，每个阵面包含90×180个阵元，阵元间距为λ/10。
