Furthermore, the electric field of a point charge is found to be the same as the linear Maxwell with or without the presence of a magnetic monopole. The causality and unitarity principles are also studied which impose constraints on the actual form of the Lagrangian density....
A uniform electric field is generated by particles trapped by an electromagnetic wave in a transverse static magnetic field B(0). The direction of the field is opposite to that of the accelerating electric field near the magnetic neutral sheet created by both the magnetic field of the wave and...

However, the focusing properties of the cycloidal mass analyzer depend on the uniformity of the electric and magnetic fields. In this paper, finite element simulation and charged particle tracing were used to investigate the effect of field uniformity on imaging performance of a cycloidal mass ...

Uniform bias magnetic field is very important for giant magnetostrictive actuators (GMA) to fully utilize the performance of giant magnetostrictive materials (GMM). However, it is difficult to keep it uniform when the length to diameter ratio (α) of the GMM is larger than 3.5, though the shap...
