RESEARCHERS HARNESS MYSTERIOUS CASIMIR FORCE FOR TINY DEVICES (2017)
Phys.org, 20.04.2017
A research team including Princeton scientists has found a way to harness the "Casimir force", a mysterious force of repulsion, predicted seven decades ago by the Dutch scientist Hendrik Casimir, and which arises from quantum effects and can be seen experimentally by placing two opposing plates very close to each other in a vacuum. At close range, the plates repel each other, which could be useful to certain technologies.
Until recently, however, harnessing this "Casimir force" to do anything useful seemed impossible…

CASIMIR FORCES OF METALLIC MICRO-STRUCTURES INTO CAVITIES (2015) (pdf)
A novel theoretical estimate of the Casimir force of a metallic structure embedded into a cubic cavity is proposed.
We demonstrate that by calculating the eigenmodes of the system we can determine the Casimir force which can be either attractive or repulsive by simply changing the geometry of the structures relative to the walls of the cavity.
In this analysis, several cases of structures are taken into account from rectangular slabs to chiral “omega” particles, and the predicted data are consistent with recent literature.
We demonstrate that the side walls of the studied cavity contribute decisively to the repulsive Casimir force between the system and the nearby top surface of the cavity. Finally, we have provided evidence that the medium embedded into the studied cavity (and especially its permittivity) can change the intensity of the Casimir force, while its repulsive nature once established (thanks to favorable geometrical features) remain quite robust.
