Complex refractive indices of Saharan dust samples at visible and near UV wavelengths: a laboratory study

We have retrieved the wavelength-dependent imaginary parts of the complex refractive index for five different Saharan dust aerosol particles of variable mineralogical composition at wavelengths between 305 and 955 nm. The dust particles were generated by dispersing soil samples into a laboratory aerosol chamber, typically yielding particle sizes with mean diameters ranging from 0.3 to 0.4 μm an...

Deterministic and Probabilistic Inversion at Long Wavelengths

In contrast with the scalar wave case, the scattering of elastic waves in the long wavelength limit yields data containing a surprising amount of information concerning the nature of the scatterer. We will consider both deterministic and probabilistic versions of the inversion problem pertaining to the above scattering problem. The deterministic version provides theoretical insight into the "bl...

Immersion Meta-Lenses at Visible Wavelengths for Nanoscale Imaging.

Immersion objectives can focus light into a spot smaller than what is achievable in free space, thereby enhancing the spatial resolution for various applications such as microscopy, spectroscopy, and lithography. Despite the availability of advanced lens polishing techniques, hand-polishing is still required to manufacture the front lens of a high-end immersion objective, which poses major cons...

Studying Envisat Attitude with Sciamachy Limb-scatter Measurements

High pointing accuracy is a prime prerequisite of high quality remote sensing of atmospheric constituents using limb viewing instruments. SCIAMACHY limb measurements were affected by limb tangent height errors of up to 3 km during the initial phase of the Envisat mission. These errors were caused by inaccurate satellite attitude information and possibly an instrument misalignment. Retrieval of ...
