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.
