中文摘要：

特种泡沫幕干扰实验研究中发现，构成泡沫幕的气泡半径越小，泡沫幕的干扰效果越好。本文通过探讨气泡半径、气泡液层厚度等结构参数对气泡中电磁波全反射发生概率的影响，从理论上解释了上述现象的成因，并建立了气泡结构性能参数指标η；据此提出了优化泡沫幕干扰性能的实用方法，并预测到该方法潜在的干扰性能退化风险，为彻底消除这一风险分析得出了关于η的可行值域。

英文摘要：

Special Foam Screen （SFS）jamming experiments show that the SFS has better jamming effect if the bubbles in SFS have smaller radius. By investigating the relationship between the bubble structure parameters （radius, liquid thickness, etc.） and the probability of the electromagnetic-wave total reflection, the reasons for above phenomenon are explained and analyzed in theory. A new parameter （η） which describes the structure characteristic of bubbles is defined. Furthermore, a practical method is proposed for improving the jamming effect of SFS. The potential risk of jamming performance degeneration of the method is also forecasted. In order to avoid the risk, feasible region of η is obtained through analysis.
