Modelling Carbon Nanotube coated structures. Comparison of simulation methods

Carbon Nanotubes (CNT) and graphene as a whole have been of interest since their discovery due to their unique properties. These include, but are not limited to: high electron mobility in room temperatures, relatively high thermal conductivity and possibly the highest resistance to mechanical stress. Hence, it is important to properly model structures and systems that might use graphene in future. This paper presents the comparison of several simulation methods in different programs. Special attention has been paid to calculating Radar Cross Section (RCS) of modelled structures.

An approach to surface waves velocity dispersion in inhomogeneous material surfaces

The paper presents a consistent method for modelling the changes in macroscopic parameters produced by material and impurity modified surfaces. The method, based on the surface fluctuation waves techniques of lattice displacements, is structurally suited to accommodate a variety of conditions existing at real surfaces, including inhomogeneity through the depth and topographic irregularities. The resulting model formulation provides a basis for an interpretation of the observed surface wave propagating properties and is especially useful to obtain SAW velocity dispersion.
