We study the amplitude and phase signals detected in infrared scattering-type near field optical microscopy (s-SNOM) when probing a thin sample layer on a substrate. We theoretically describe this situation by solving the electromagnetic scattering of a dipole near a planar sample consisting of a substrate covered by thin layers. We perform calculations to describe the effect of both weakly (Si...

We develop an anisotropic perfectly matched layer (PML) method for solving the time harmonic electromagnetic scattering problems in which the PML coordinate stretching is performed only in one direction outside a cuboid domain. The PML parameters such as the thickness of the layer and the absorbing medium property are determined through sharp a posteriori error estimates. Combined with the adap...

This supplemental material provides additional figures and derivations that complement our paper. The main paper includes indicative examples from the full set of plots contained in this document. We present graphical plots that detail how each of the Paper BSDF’s components contribute to closely replicating our BSDF measurements for paper. We also offer comparison plots for Lambertian/Rough Gl...

Acoustic scattering layers are ubiquitous, horizontally extensive aggregations of both vertebrate and invertebrate organisms that play key roles in oceanic ecosystems. However, currently there are no conventions or widely adaptable automatic methods for identifying these often dynamic, spatially complex features, so it is difficult to consistently and efficiently describe and compare results. W...

Feature film: Thin films made by exponential layer-by-layer growth display high diffusivity and can be readily infiltrated with inorganic nanoparticles. They can sequestrate molecular systems from solution as a function of the composition of their layers, while providing intense surface-enhanced Raman scattering (SERS) signals (see picture).

We revisit here how Raman microscopy can be used to estimate the H content in hydrogenated amorphous carbon layers. The H content was varied from 2 at.% to 30 at.%, using heat treatments from room temperature to 1300 K and was determined independently using ion beam analysis. We examine the correlation of various Raman parameters and the consistency of their thermal evolution with thermodesorpt...

We have measured the transport and quantum mobility in Si delta doped samples as a function of the doping concentration and the thickness of the doping layer. The results are compared with mobility calculations which show that the ionized impurity scattering rate is determined by the fluctuations in the charge distribution of the delta layer instead of the full charge distribution itself.

[1] A fast radiative transfer model has been developed for simulating high-resolution absorption bands. The first scattering radiance is calculated accurately by using the higher number of layers and streams for all required wave number grids. The multiple-scattering component is extrapolated and/or interpolated from a finite set of calculations in the space of two integrated gaseous absorption...

In this paper, we report the first systematic comparison of 12-year modeled dust extinction profiles vs. Raman lidar measurements. We use the BSC-DREAM8b model, one of the most widely used dust regional models in the Mediterranean, and Potenza EARLINET lidar profiles for Saharan dust cases, the largest one-site database of dust extinction profiles. A total of 310 dust cases were compared for th...

In the Part II of this study, the reverse Monte Carlo algorithm was applied to onedimensional, multi-layer media. The time-resolved reflectance exhibits a direct correlation between the signal magnitude and the travel time to the layer interface if the ballistic photons encounter a strongly scattering layer. Furthermore, it is found that even with a symmetric radiative property distribution in ...
