However, it is challenging to manipulate the dielectric permittivities of most materials using external fields. In contrast, the magnetic permeabilities of ferrofluids can be readily tuned by magnetic fields, which opens up the possibility of magnetic-field tuning of the Casimir force. Here, we ...

In the magnetic excitation method, an ac magnetic field is generated by flowing an ac current with a constant amplitude through the coil. This is typically realized by a coil driver with a voltage-to-current (VI) converter, where the coil current is continuously adjusted by a feedback control...
Using a magnetic field as a trigger has several advantages over other modes of operation. Magnetic actuators can generate strong force and displacement with low power consumption, and they are less prone to electrical heat loss and high-voltage failure. Moreover, the actuation parts and magnetic ...
By arranging the eight optimized elements, a device that can generate the deflection of the reflected beam with a deflection angle of 16° was constructed. Far-field scattering was obtained, and a reflecting lens was constructed on the basis of these eight grating elements. We further optimized ...

It is shown that for real magnetodielectric materials only the magnetic properties of ferromagnets can influence the Casimir pressure. This influence is accomplished through the contribution of the zero-frequency term of the Lifshitz formula. The possibility of the Casimir repulsion through the vacuum ...
