本文导出了被亚波长狭缝隔开的两个宏观金属体或膜之间光致吸引力的显式解析表达式。对于主TM模，得到的解析表达式与数值计算结果吻合得很好。当光通过亚波长狭缝传播时，在金属表面激发的等离子体激元-极化激元的相互作用产生了这种力，其作为具有负光压力的力。对这种光诱导吸引力的估计表明，这种力足以使测量和实际应用成为可能。
An explicit analytical expression of a light-induced attractive force between two macroscopic metal bodies or films separated by a subwavelength slit has been derived. The analytical expression obtained agrees well with the numerical calculations for the main TM mode. This force, which acts as a force with negative light pressure, arises by the interaction of plasmon-polaritons excited at the surface of metal when light propagates through the subwavelength slit. Estimations of this light-induced attractive force show that the force is sufficient to enable measurements and practical applications.
