Pulsed EM radiation from a traveling-current plasmonic nanowire

Abstract

Pulsed electromagnetic (EM) radiation from a traveling-current plasmonic-wire segment is studied ana-lytically using the unilateral Laplace-transform technique. This approach yields closed-form expressionsthat can be readily evaluated for given configurational and excitation parameters, thereby revealingphysical insight into the time-domain (TD) EM radiation behavior of a plasmonic nanowire. Illustrativenumerical examples concerning pulsed EM fields radiated from a gold nanowire are given and discussed.Pulsed electromagnetic (EM) radiation from a traveling-current plasmonic-wire segment is studied ana-lytically using the unilateral Laplace-transform technique.
