Abstract
The lifetime of a surface plasma wave (SPW) on a semi-infinite air/metal interface is calculated. The calculation is based on the assumption that SPW has a real frequency and a complex propagation constant. Thus the lifetime of the SPW can be calculated in a wide spectrum range from 0.1 to 10 μm. Two different metals (aluminum and silver) have been used separately as the media for generating the SPW. Within the spectrum of visible light, the lifetime of the SPW on the air/metal interface is in subpicoseconds.
