The amplitude modulation of three-dimensional (3D) dust ion-acoustic wave (DIAW) packets is studied in a collisionless magnetized plasma with inertial positive ions, superthermal electrons and negatively charged immobile dust grains. By using the reductive perturbation technique, a 3D-nonlinear Schrödinger equation is derived, which governs the slow modulation of DIAW packets. The latter are found to be stable in the low-frequency ðx\x c

The amplitude modulation of three dimensional (3D) dust ion-acoustic wave (DIAW) packets is studied in a collisionless magnetized plasma with inertial positive ions, superthermal electrons and negatively charged immobile dust grains. By using the reductive perturbation technique, a 3Dnonlinear Schrödinger (NLS) equation is derived, which governs the slow modulation of DIAW packets. The latter are found to be stable in the low-frequency (ω < ω c ) regime, whereas they are unstable for ω > ω c , and the modulational instability (MI) is related to the modulational obliqueness (θ ). Here, ω (ω c ) is the nondimensional wave (ion-cyclotron) frequency. It is shown that the superthermal parameter κ, the frequency ω c as well as the charged dust impurity (0 < µ < 1) shift the MI domains around the ω − θ plane, where µ is the ratio of electron to ion number densities. Furthermore, it is found that the decay rate of instability is quenched by the superthermal parameter κ with cut-offs at lower wave number of modulation (K), however, it can be higher (lower) with increasing values of µ (ω c ) having cut-offs at higher values of K.

“…To improve the communication performance during the re-entry process, many works on the propagation characteristics of electromagnetic (EM) waves in an inhomogeneous plasma sheath have been carried out and numerous achievements have been reported [ 7 , 8 , 9 ]. In addition, the materials of the reentry vehicle surface appear to be ablated as a result of the high temperature, which results in many ablative particles being produced [ 10 ]. The essence of ablative particles is dust particles.…”

The propagation characteristics of terahertz (THz) waves incident vertically into inhomogeneous and collisional dusty plasma with a ceramic substrate are studied using the scattering matrix method (SMM). The effects of the incident wave frequency and plasma parameters, such as the maximal electron density, dust particle density, dust particle radius and collision frequency, on the reflectance and transmittance of THz waves in the dusty plasma are discussed. In addition, the differences of the propagation properties in the dusty plasma, with and without ceramic substrate, are analyzed. Meanwhile, the differences of the propagation properties in dusty plasma and common plasma, respectively, with ceramic substrate are also compared. Simulation results show that the substrate and dust particles have significant influence on the propagation characteristics of THz wave in plasma sheath. Finally, the transmission increases with the increase of electron density, dust density, dust particle radius and collision frequency.
