Effects of substrate and graphene surface roughness on graphene sheet plasmons

Nanoscale Systems: Mathematical Modeling, Theory and Applications

Similarity:

We study the effects of roughness in a graphene layer that lies on a substrate with rough surface on the dynamic response of such a structure. Using an analytical expression for the dielectric function of flat graphene in the optical limit allows us to tackle the effects of roughness on the sheet plasmon in graphene. We first formulate a stochastic eigenvalue problem for the plasmon dispersion in terms of the roughness parameters that include both the auto– and the cross–correlation...

Fusion based analysis of ophthalmologic image data

Jiří Jan, Radim Kolář, Libor Kubečka, Jan Odstrčilík, Jiří Gazárek (2011)

Kybernetika

Similarity:

The paper presents an overview of image analysis activities of the Brno DAR group in the medical application area of retinal imaging. Particularly, illumination correction and SNR enhancement by registered averaging as preprocessing steps are briefly described; further mono- and multimodal registration methods developed for specific types of ophthalmological images, and methods for segmentation of optical disc, retinal vessel tree and autofluorescence areas are presented. Finally, the...
