摘要

We present a rigorous closed-form solution to complete the fundamental theory on the transient surface plasmons polaritons (SPP) present on a metal interface, in addition to the conventional long-range SPP, launched by scattering of a metal subwavelength slit. We demonstrate that the Maxwell equations solution includes a transit SPP with complex-valued Exponential Integral envelope by computing the Sommerfeld branch-cut integrals. Physically, the transient SPP is the cylindrical wave initially radiated from the source line, which losses its energy to pumping the long-range SPP mode in the propagation. Its varying damping rate is comparable with existing numerical and approximate results.
