JUNE 1997 REPORT FOR






W. CHARLES SYMONS, III










As was previously described in last month's report, a Finite Element Method (FEM) model was developed to simulate a two-dimensional Near-Field Scanning Optical Microscope (NSOM). Additionally, a preliminary report detailing this model and some results has been made available in HTML format.

During May, in addition to the laser dermatome grant mentioned last month, another grant was submitted requesting funds for a piezoelectric nanopositioning stage to be utilized with the actual Near-Infrared NSOM instrument being developed. In conjunction with this grant, a preliminary dialogue has begun with Dr. Lance DeLong in the Physics department to collaborate on imaging some material samples currently being developed.

Finally, an experiment was discussed with Dr. Keith Whites in Electrical Engineering to fully investigate the near-field focusing effect of thin-wire samples within NSOM instruments seen in previously developed NSOM models. Due to the simplicity of this experiment and the fact that the majority of equipment is currently available, this experiment should be completed by the end of the summer.
