OCTOBER 1997 REPORT FOR

W. CHARLES SYMONS, III

First and foremost, during September, the NSOM stage purchasing request was finally submitted. As mentioned previously, two alternate vendors were investigated and the Melles Griot system was revealed to be the superior system. More specific results of this investigation can be seen online in the NSOM stage buying proposal. In addition to ordering the NSOM stage equipment, the laser dermatome control system design was finalized and the necessary parts were subsequently ordered and should arrive soon so that setup and testing can begin.

In addition to the above equipment demands, the near-field x-band experiment was partially designed and most of the necessary equipment was located. At this point, preliminary experimental runs should be performed within the next couple of weeks followed shortly by the final experiment.

With the tenth anniversary of the University of Kentucky's Computational Sciences on October 1, 1997, several computational NSOM movies were generated for demonstration purposes. These movies are posted below in Quicktime format and are described as follows:

€ Simulated NSOM collection where a fiber probe is scanned above a thin wire and the image is a Moment Method generated image of a thin wire.

€ FDTD simulation of Source pulse incident on PEC plate with subwavelength aperture.

€ FDTD simulation of thin wire illuminated by a subwavelength aperture.

€ FDTD simulation of radiation emitted through a subwavelength aperture (No Sample).

€ Difference between FDTD thin wire simulation and simulation with no sample.
