The method principal component (PCA) allows to allocate from a matrix of these several objects with a large amount of signs only 1–3 vectors containing 90–95% of information. Usually measuring problem of assessment of these main components is solved by the iterative NIPALS procedure or the algebraic SVD procedure, however both of these methods often give ambiguous estimates. For the purpose of elimination...
Integral equation technique of classical electrodynamics and the Landauer-Buttiker formalism of quantum transport were applied to develop electromagnetic scattering theory for a finite-length nanowire with embedded mesoscopic object. The theory is valid for a rather wide range of nanostructures, such as nanowires, nano-loops, nano-ribbons, Vivaldi antennas, etc.
