Role of epsilon-near-zero substrates in the optical response of plasmonic antennas (2016, positive): “where L is the nanorod length, δ is the evanescent extension of the resonant antenna mode beyond the physical dimensions of the nanorod, and L 2δ accounts for the effective antenna length [41,48,49].”
