Surface Plasmon Polaritons: Creation Dynamics and Interference of Slow and Fast Propagating SPPs at a Temporal Boundary
Abstract
We establish the theoretical framework for a material system that supports surface plasmon polaritions (SPPs) excited by a dipole excitation, where the media configuration suddenly changes at a temporal boundary. We employ three-dimensional Green's function analysis in the Laplace transform domain. We use this framework to demonstrate dynamic SPP formation and time-boundary-induced interference of slow and fast propagating SPPs. This analysis provides insight into how SPPs are formed in time and how they interfere at a temporal boundary.
