5G无线通信使用28GHz频带中的电磁（EM）波，并且从高方向性（增益）天线辐射的EM波因此被墙壁在镜面方向上散射。如果在发射和接收天线之间存在障碍物，则无线通信质量恶化，因为接收器既不能接收直接波也不能接收反射波。为了提高无线通信质量，应用阵列天线理论设计了一种电磁散射墙。此外，电磁散射墙的最佳配置是使用遗传算法设计的，而不需要大量的计算由电磁仿真器。
: 5G wireless communications use electromagnetic (EM) waves in the 28 GHz band, and the EM waves radiated from high-directivity (gain) antennas are hence scattered in a specular direction by walls. If there are obstructions between the transmitting and receiving antennas, the wireless communication quality is deteriorated since the receiver can receive neither direct waves nor reflected waves. In this paper, an EM scattering wall is designed by applying array antenna theory to improve the wireless communication quality. Moreover, the optimum configuration of the EM scattering wall is designed by using the genetic algorithm without a large amount of calculation by an EM simulator.
