JUNE 1996 REPORT FOR

W. CHARLES SYMONS, III

As described in my May monthly report, a single point Near-Field Scanning Optical Microscope (NSOM) model was developed utilizing the Finite Difference Time Domain (FDTD) method. During the past month, this code was further developed into a fully scanning model. Due to the long run times necessary for this code, full results have not been gathered at this time. Instead, this time is now being spent parallelizing the FDTD code for the Convex Exemplar. At this point, this parallel model is still a work in progress but should be up and running very shortly. Once accurate results are obtained, they will be posted here as well as in an updated version of the paper entitled Electromagnetic Scattering Analysis of PEC Objects Within the Near-Field of an Aperture Illuminated by an Incident Plane Wave Utilizing FDTD Methods.

In addition to enhancing the FDTD NSOM model, this past month has also been spent enhancing my web pages which are all accessible from my home page. In particular, my latest Pittsburgh Conference presentation entitled NEAR INFRARED SCANNING NEAR-FIELD MICROSCOPIC IMAGING has been incorporated into a web page utilizing frames. Currently the image captions have not been completed but they will be linked in as soon as possible.
