Propagation Matrix Method Study on THz Waves Propagation in a Dusty Plasma Sheath

Terahertz (THz) waves propagation in a stratified media slab containing dusty plasmas are investigated using the propagation matrix method. The dispersive permittivity of conductors and dusty plasmas at THz frequencies are given. After the validation of the method is performed, the propagation properties of aluminum coated by dusty plasmas with and without vacuum interlayer are compared. The THz reflection and transmission coefficients for a dusty plasma slab with different medium parameters are discussed.
