Abstract
Abstract The proposed concept of Raman probe for nearfield optical microscopy raises the question about the similarity of fields acting on specimens deposited at the tip apex and contacting surface. The signal generated at these two close but different points is defined by local fields, so it is the ratio of the fields at these points, that is the quantity of interest here. This work is concerned with the application of a simple dipole model for the analysis of the ratio of fields at the tip apex and at contacting surface as a function of their separation.
