Non-local energy transport in tunneling and plasmonic structures

Non-local energy transport in tunneling and plasmonic structures: "Winston Frias, Andrei Smolyakov, Akira Hirose
Various definitions of the velocity of propagation of the electromagnetic field have been adopted in experimental and theoretical studies of tunneling and plasmonic systems. Tunneling problems are often analyzed by invoking the group delay (or dwell time) velocities. On the other hand, slow light ... [Opt. Express 19, 15281-15296 (2011)]"
