Energy dissipation and power deposition of electromagnetic waves (EMW) in the reentry plasma sheath provide an opportunity to investigate ‘communication blackout’ phenomena. Based on a finite element method (FEM) simulation, we analyze variation of EMW energy dissipation and power deposition profiles dependent on the wave polarization, wave incident angle, plasma density profile and electron collision frequency. Cutoff and resonance of EMW in the plasma sheath are crucial in explaining the regulation of energy dissipation and power deposition.

等离子体鞘层中电磁波的能量耗散和功率沉积

折返等离子体鞘中的电磁波（EMW）的能量耗散和功率沉积为研究“通信中断”现象提供了机会。基于有限元方法（FEM）仿真，我们分析了EMW能量耗散和功率沉积曲线的变化，该变化取决于波的极化，波入射角，等离子体密度曲线和电子碰撞频率。等离子体鞘中EMW的截止和共振对于解释能量耗散和功率沉积的调节至关重要。
