Thin films of aluminum were exposed in short increments to a plasma environment using a semiconductor plasma asher. The process gas was a mixture of air and oxygen. The total exposed oxygen fluence was 1.2 × 10 21 oxygen atoms cm −2 accumulated ov

In this work full wave expressions are derived for the incoherent diffuse scatter cross sections (per unit area) for waves transmitted across rough surfaces. Both the like- and cross-polarized cross sections are considered since the surfaces are roug

The tilt modulations of the like- and cross-polarized cross-sections for arbitrarily oriented resolution cells are determined using the unified full-wave approach. A broad family of non-Gaussian rough surfaces characterized by the gamma surface heigh

The unified full wave approach is used to generate polarimctric images of composite rough surfaces illuminated by high resolution radar (i.e., real or synthetic aperture radars with small effective footprints). The unified full wave solutions account

The unified full wave approach is used to determine the tilt modulation of the like- and cross-polarized (high-resolution) radar backscatter cross sections for the rough sea surface. Real or synthetic aperture radars (SARs) with small effective footp

Using variable angle spectroscopic ellipsometry and atomic force microscopy (AFM), the surface roughness and oxidation of aluminum and titanium thin films have been studied as a function of substrate deposition temperature and oxygen plasma exposure.

Research on the detection of heavy metals in soils and water using laser-induced breakdown spectroscopy (LIBS) has been carried out. LIBS is based on a Nd:YAG laser operating at 50-100 mJ at /spl lambda/=1.06 /spl mu/m. The beam is focused on the sur
