A very electrically small, active open cylindrical coated nanoparticle model is constructed, and its electromagnetic properties are investigated in the visible frequency band. Its optical response under both planewave and electric dipole antenna excitations shows very strong dipole behavior at its lowest resonance frequency. The scattering cross section at that dipole resonance frequency is increased...
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...
