Paper Abstract

The near-field scanning optical microscope (NSOM) has been developed to extract optical information from a nanometric area of sample. The amount of information contained in an NSOM image is potentially vast but it could not yet be fully exploited because of the need for a more complete understanding of the effects of the probe-sample interaction on the imaging process. A better understanding will lead to an unambiguous analysis of an NSOM image and will make the NSOM a reliable imaging tool. In this paper, we present the analysis of NSOM imaging through the numerical calculation based on an electromagnetic-theory-based algorithm,called Finite-Difference Time-Domain method (FDTD).
