揭示了一种新的光诱导引力，它是一种具有负光压的力。当横磁模通过两个金属体之间的亚波长狭缝传播时，在金属表面激发的等离子体激元相互作用产生力。给出了亚波长TE模沿狭缝沿着传播时作用在狭缝金属壁上的排斥力的估算。本文导出了被亚波长狭缝隔开的两个宏观金属体或薄膜之间的光致力的解析表达式。这些力可用于在真空或电介质中操纵金属宏观、微观和纳米物体。这些光诱导力的估计表明，这些力是足够的测量和实际应用。
A novel light-induced attractive force which acts as a force with negative light pressure has been revealed. The force arises by the interaction of plasmon polaritons which are excited at the surface of metal when a transverse magnetic mode propagates through a subwavelength slit between two metal bodies. The estimation of the repulsive force acting on the metal walls of the slit in the case of subwavelength TE mode propagation along the slit is presented. The explicit analytical expressions of light-induced forces between two macroscopic metal bodies or films separated by a subwavelength slit have been derived. These forces could be used to manipulate metallic macro-, micro- and nano-objects in vacuum or in a dielectric medium. Estimations of these light-induced forces show that the forces are sufficient for measurements and practical applications.
