The transmission characteristics of terahertz waves in inhomogeneous magnetized dusty plasma are studied by using the shift-operator finite-difference-time-domain (SO-FDTD) method. The Epstein distribution model is employed to simulate the electron density distribution in dusty plasmas. The results given by the SO-FDTD method are in good agreement with those gotten by the Wentzel–Kramers–Brillouin method. Both the left-hand and right-hand circularly polarized (LCP and RCP) waves are taken into account. The transmission characteristics of RCP waves are more complicated than LCP waves. The numerical results show that all the physical parameters, such as the electron density, dust particle density, dust particle radius, effective collision frequency, electron relaxation rate and external magnetic field intensity, and so on, can affect the propagation, absorption and reflection of terahertz waves in dusty plasma. These theoretical results may be useful for alleviating the “blackout” problem and improving electromagnetic waves communication.
