【摘要】 本文数值仿真了分布于封闭金属舱体内ISM频段无线传感器点对点传输和并发传输两种传输情形,对比分析了传统通信方式和时间反演通信方式下的电磁能量空间分布;仿真结果表明,利用时间反演电磁波传输技术可有效抑制封闭金属舱体内的多径干扰,并能使相距一定距离的两个传感器实现共存与并发传输。更多还原

【Abstract】 This article numerically simulates point-to-point transmission and concurrent transmission of ISM band wireless sensors operating in a closed metal cavity,and comparative analysis is made for the electromagnetic energy distribution of the traditional communication method and time reversal scheme.Simulation results show that time reversal electromagnetic waves transmission technology can effectively suppress the multipath interference caused by the closed metal cavity,and it can realize concurrent transmission and coexistence between two spaced wireless sensors.更多还原
