Abstract

Using kinetic theory, the dispersion properties of dust ion-acoustic (DIA) wave propagation in the dusty plasma including electrons, ions, and dust particles are investigated. We obtain the dispersion relation of the DIA wave in the plasma with q-distribution. In the limit q → 1, the results are in agreement with Maxwellian distribution results. The wave frequency decreases as the nonextensive index q increases, particularly for the high magnitude of the q index. The phase velocity of the wave is achieved for short and long wavelengths. The wave frequency enhances by increasing the ion to electron density ratio.
具有q分布的尘埃等离子体中尘埃离子-声波色散特性的研究
利用动力学理论,研究了尘埃离子声(DIA)波在含电子、离子和尘埃粒子的尘埃等离子体中的色散特性。得到了DIA波在等离子体中具有q分布的色散关系。在极限q→1时,结果符合麦克斯韦分布的结果。波的频率随着非扩展指数q的增加而减小,特别是对于高强度的q指数。短波和长波的相速度是可以得到的。随着离子与电子密度比的增大,波的频率增大。
