Multilayer Reflectivity
... When ~k is complex, this equation shows that the imaginary part of ~k leads to exponential damping of the time-averaged Poynting vector. With the addition of the second term in the brackets above, we see that energy is transported in a direction that differs from the direction of the wave, which is ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
