Reactive energy in non-diffracting localized waves
Peeter Saari, Ioannis Besieris
It is well known that although the group velocity of structured light pulses propagating in vacuum can be subluminal or superluminal, the upper limit of the energy flow velocity is…

Reexamination of energy flow velocities of non-diffracting localized waves
Peeter Saari, Ott Rebane, Ioannis Besieris
A universal relation has been established between the local energy transport velocity along the direction of propagation and the group velocity of scalar and vector-valued propagat…
