Abstract
The Auxiliary Differential Equation Finite Difference Time Domain (ADE-FDTD) method is applied to study the electromagnetic scattering of a dusty plasma sheath with Epstein distribution. The charging response factor of dust particles and angular plasma frequency of the dusty plasma are functions of space-varying electron density with an Epstein profile. The verification of the numerical ADE-FDTD algorithm for the dusty plasma is given. The propagation properties of Terahertz (THz) waves through a dusty plasma slab affected by the characteristic parameter and modulation factor of the Epstein distribution are discussed. The absorption coefficients of the slab influenced by the electron density, density of dust particles, and effective collision frequency are studied. It is shown that Terahertz waves may be an efficient tool for high density dusty plasmas detection and diagnostics.
