Collision absorption and resonance absorption of electromagnetic waves by array plasma

摘要: This article described the experiment on absorption of 1–18GHz electromagnetic (EM) waves by array plasma which was produced many standard commercial fluorescent lamps placed directly against each other in two rows. Weak reflection and strong were observed. Predictive peak electron density collision frequency discussed compared with measurement. The results indicated that single-pass reached maximum about 10dB, when incident approached to frequency. Resonance took place case properties varying along electric field wave,
