Abstract:
The far-field transmission pattern of a tapered optical tip with small aperture (radius approximately < 40 nm) is modelled by solving Maxwell's equations in the radiation zone with boundary conditions appropriate to the conical geometry. The model is able to reproduce the large differences between the S and P polarizations observed previously in the emission profile of such a tip [Obermüller and Karrai. Appl. Phys. Lett. (1995) 67, 3408].
