Abstract—In this paper, the collisional absorption mechanism of electromagnetic-wave in plasma for DC discharge type is studied with numerical method. The computation model of the electromagnetic-wave collisional absorption in the DC discharge plasma is founded. The FDTD method is presented for simulating the collisional absorption of electromagnetic-wave energy in the one-dimensional inhomogeneous plasma by DC discharge generator. The emulational results illustrate that the inhomogeneous plasma electron density which is produced by DC discharge around the opening space could be approximate to 1014-1015cm-3, and the plasma can absorb the energy of electromagnetic-wave in the wide bandwidth by collisional absorption.

Index Terms—Plasma, DC discharge, electromagnetic-wave, collisional absorption.
