Abstract

The evanescent field surrounding an exposed planar waveguide in silica is accurately measured using scanning near field optical microscopy (SNOM) and compared to models of the field distribution. Distortions in the field due to edge effects and the proximity of the mode to the surface are all detected. The characterized field is use to quantitatively explore the difference in collection efficiency between contact mode SNOM and intermittent contact mode SNOM. A strong correlation between tip oscillation amplitude and detection efficiency is determined. Microsc. Res. Tech., 2007. © 2007 Wiley‐Liss, Inc.

A ®eld instrument was designed and ®eld tested for measuring the applied wind load on trees and surface-mounted obstacles in a natural boundary layer. Using this instrument, the eect of vegetation porosity on the drag coecient of small conifer trees (h 1 . 4 m) was determined directly in the ®eld. D
