Description
Summary:Dust particles generated from the thermal protection layer greatly influence the propagation of electromagnetic (EM) waves in the plasma sheath. This paper presents the first calculation of the effects of these dust particles on microstrip antenna radiation. On the basis of an integrated model of the ablation plasma sheath and C-band microstrip antenna, the ray tracing method is used to obtain the disturbed electric field in a traditional plasma and a dusty plasma (with different dust parameters). The results show that the dust particles cause greater attenuation of incident waves, and different dust parameters have different effects on the penetrating electric field. This study reveals that the ablation of the thermal protection layer changes the electromagnetic properties of the plasma sheath, and the generated dust particles should not be ignored in the electromagnetic computation.
