Illustration of circularly polarized pulse traveling in a fluid of diamagnetic molecules located in time-dependent external electric field and magnetic field
both parallel to the propagating direction of the pulse.
For the three-piece product , the fluid acts as a time wave plate. At t0, the incident pulse splits into a refracted one and a reflected one. At t1, the two pulses further split into four.
