Re-visiting Veselago´s prediction of Negative Radiation Pressure: Does the momentum of light reverse in left-handed media?

In 1968, Veselago postulated the existence of left-handed electromagnetic media bearing the unique ability to sustain electromagnetic plane waves with contradirectional power and phase flow (V. Veselago, Sov. Phys. Usp., 10, 509). Counter-intuitive optical properties predicted to be associated with left-handed media include negative refraction, a reversed Doppler effect, a reversed Cherenkov effect, and negative radiation pressure. While the phenomenon of negative refraction has been well-studied and realized across the electromagnetic spectrum using engineered structures known as metamaterials, the other traits predicted for left-handed media have received comparatively little attention.
