摘要

We consider radiation emitted by an electric dipole close to a mirror. We have studied the field lines of thenPoynting vector, representing the flow lines of the electromagnetic energy, and we show that numerous singularitiesnand subwavelength optical vortices appear in this energy flow pattern. We also show that the fieldnline pattern in the plane of the mirror contains a singular circle across which the field lines change direction.n© 2009 Optical Society of America
