The propagation of the electromagnetic field in fully coated near field optical probes was analyzed. It was proved that these structures allow nonzero modal emission of the electromagnetic field through a 60-nm thick metallic layer. It was also found that a high confinement of the electromagnetic energy can be reached in the near field, when illuminated with radially polarized light.
