Interference between light waves is one of the widely known phenomena in physics, which is widely used in modern optics, ranging from precise detection at the nanoscale to gravitational-wave observation. Akin to light, both classical and quantum interferences between surface plasmon polaritons (SPPs) have been demonstrated. However, to actively control the SPP interference within subcycle in time (usually less than several femtoseconds in the visible range) is still missing, which hinders the…

This article investigates the application of aggregation topology methods to the representation of network domains in a dynamic scenario and evaluates the combined effect of topology aggregation and non-instantaneous topology information update on the routing performance of a multi-domain network.
