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