近年来，短距离无线通信在我们的生活中使用得越来越频繁。但是电磁场也有一些缺点。其中一个不利因素是健康问题。许多研究表明，用于通信的电磁场波可能会损害我们的健康。在大多数医院，由于电磁干扰，他们还禁止使用移动的电话和广域网。因此，本文研究了利用超声波代替电磁场波进行空气中的无线通信。提出了一种用于超声波通信系统仿真的交替方向隐式时域有限差分法（ADI-FDTD）。ADI-FDTD模拟可以更好地理解超声信号的行为。实验数据也与模拟进行了比较。结果表明，这样的系统是可行的，在原则上使用超声波通信。
In recent years, short range wireless communications have been used more and more frequently in our life. But the electromagnetic fields waves also have some disadvantages. One of these disadvantages is health problems. Many studies shows the electromagnetic field waves using for communication may damage our health. And in most hospitals, they also have bans on the use of mobile phones and wide area networks because of Electromagnetic Interference. So in this paper, we studied the use of ultrasound for wireless communication in air, instead of using electromagnetic field wave. An Alternating-Direction Implicit Finite-Difference Time-Domain (ADI-FDTD) method is developed to simulate the ultrasonic wave communication system. The ADI-FDTD simulations make it possible to better understand the behavior of an ultrasonic signal. Experimental data is also presented to compare with simulation. The results show that such a system is feasible in principle for communications using ultrasound.
