Abstract
A theoretical investigation of plane-wave electromagnetic scattering in active dielectric cylinder predicted the existence of anomalous resonances that occur at discrete plane-wave angles of incidence. These resonances may be understood from a “leaky wave” phase matching boundary condition. Experiments using finite-diameter pump and probe laser beams verified the existence of these resonances with enhancements of the scattered field. Optical pumping of dye solution was used to provide the gain. The threshold of each resonant mode was found to be a function of the radius of cylinders used.
