We analyze two basic aspects of a scanning near-field optical microscope (SNOM) probe's operation: (i) spot-size evolution of the electric field along the probe with and without a metal layer, and (ii) a modal analysis of the SNOM probe, particularly in close proximity to the aperture. A slab waveguide model is utilized to minimize the analytical(More)
The scanning near-field optical microscope (SNOM) has been tested experimentally for a wide variety of applications, but, to date, there has been little work done on the numerical or analytical modeling of the optical field as it propagates throughout the SNOM probe. Therefore, the fabrication on the probes relies more on trial and error than on clear(More)
