【 摘 要 】

The time-domain surface impedance for a plane-wave incidence on a half-space with conductive and plasmonic properties is theoretically investigated. This paper provides closed-form time-domain expressions of time-domain surface impedance values that can be readily evaluated numerically within any prescribed accuracy. Based on the surface impedance concept, time-domain responses of conductive and plasmonic half-spaces are analyzed and discussed. In this respect, changes in incident pulse shapes upon transmission and reflection against plasmonic boundaries are predicted. Numerical results for practically used metallic materials are presented.
