    • The nearly parallel orientation of the wire transition dipole moment (i.e., along the long axis of the wire) with the electromagnetic field of the excited plasmon mode (i.e., along the tip axis) leads to a much larger plasmon amplification than the orthogonal configurations [36]. This effect is balanced by the reduced amplification expected for large tip-sample distances.
