WebMay 13, 2024 · The theoretical basis for optical forces was founded by Maxwell’s electromagnetic theory in 1873, which showed that momentum transfer from an electromagnetic field to an object, due to absorption or reflection, should manifest as optical forces in the direction of propagation of electromagnetic waves. WebMay 6, 2008 · We study such forces by using an electrodynamics approach, which fully incorporates the retardation effect. As two particles approach each other, the single-particle plasmons hybridize and split into attractive bonding modes and repulsive antibonding modes, which eventually evolve into an attractive band and a repulsive band.
