  We introduce an efficient computational scheme based on Macro Basis Function
(MBF) method, to analyze the scattering of a plane wave by the V-shaped
plasmonic optical nano-antennas. The polarization currents and the scattered
fields for symmetric and anti-symmetric excitations are investigated. We
investigate how the resonant frequency of the plasmonic V-shaped nanoantenna is
tailored by engineering the geometrical parameters and by changing the
polarization state of the incident plane wave. The computational model
presented herein is faster by orders of magnitude than commercially available
finite methods and is capable to characterize also other nanoantennas
comprising of junctions and bends of nanorods.
