Paper Abstract

It is demonstrated that waveguide eigenmodes with a rotating phase may exert a longitudinal force, positive or negative, as well as a torque on the guiding structure or part of it. A general formulation of the linear and angular momentum currents flowing in the waveguide is given. Several examples are considered, including a lossy dielectric cylinder bounded inside a hollow waveguide, and a lossy dielectric fiber. The results of this study may be used for a novel type of light driven rotating machines.
