论文摘要
数值研究了尘埃声波中的泰赫兹波的传播。通过假设尘埃声波中的灰尘密度密度的鼻窦轮廓，可以使用有限差的时域方法计算传输特性。它表明，尘埃声波可以像布拉格滤波器一样起作用，以阻止特定波长的Terahertz波。过滤器的带宽取决于尘埃声波的密度曲线。
The propagation of terahertz waves in a dust acoustic wave is investigated numerically. By assuming a sinus profile of the dust number density in the dust acoustic waves, the transmission properties are calculated using finite difference time domain method. It shows that the dust acoustic wave can function similarly as a Bragg filter to block the terahertz waves of a certain wavelength. The bandwidth of the filter depends on the density profile of the dust acoustic wave.
