Abstract
We theoretically investigate the optical pressure for a dielectric fil m located in the evanescent field of a Gaussian beam. in our approach, we derive the electromagnetic fields at the boundaries of the film by solving the boundary-value problem for a system of four stratified me dia with the incidence of a Gaussian beam. We also formulate analytica lly the optical pressure exerted on a dielectric film by using the der ived electromagnetic fields. Numerical results of the optical pressure by a Gaussian beam-generated evanescent wave are presented in compari son with the plane-wave results.
