Electric field induced deformations of twisted nematic cell containing liquid crystalline material characterised by flexoelectric properties and positive dielectric anisotropy were studied numerically. Anisotropic boundary anchoring was taken into account by use of a model formula proposed for this purpose. It...

When an alternating electric field is acting upon the molecules of a dielectric material, the molecules start acting differently. They constantly realign their charges with each half period of the field applied to them. We know about these behaviors thanks to J. C. Maxwell, who introduced t...
The electric field control of magnetization is of significant interest in materials science due to potential applications in many devices such as sensors, actuators, and magnetic memories. Here, we report magnetization changes generated by an electric fi
