The nanosecond response of a PbTiO(3)/SrTiO(3) ferroelectric/dielectric superlattice to applied electric fields is closely linked to the dynamics of striped domains of the remnant polarization. The intensity of domain satellite reflections observed with time-resolved x-ray microdiffraction decays in 5-100 ns depending on the magnitude of the electric field. The piezoelectric response of the sup...

In this paper‎, ‎the static bending‎, ‎free vibration‎, ‎and dynamic response of functionally graded‎ ‎piezoelectric beams have been carried out by finite element method‎‎under different sets of mechanical‎, ‎thermal‎, ‎and electrical‎ ‎loadings‎. ‎The beam with functionally graded piezoelectric material‎ ‎(FGPM) is assumed to be graded across the thickness with a simple‎ ‎power law distributio...

The electromagnetic momentum of a point electric dipole in a uniform magnetic field of strength B0 of infinite extent is equal to B0 × p/4, i.e., to half the electromagnetic momentum of a macroscopic dipole of electric moment p in the same field. This result is obtained using three different methods which provide a test of the internal consistency of electrodynamics with regard to the handling ...

A series of three articles present an innovative way to build advanced functionally graded materials (FGM) based on polymer/ceramic composites tailored by electrophoresis from the process principle their field grading application in power electronics. In this Part 2, it was studied impact a non-uniform electric high-k SrTiO3 particle organization within epoxy matrix. that purpose, DBC substrate...

A theoretical study of the relativistic cyclotron motion occurring in a uniform magnetic field and an oscillating electric field of arbitrary polarization is performed, which aims at determining the effect of the ellipticity and the strength of the electric field upon the integrability or nonintegrability of the system. Unless a circularly polarized electric field is used, the cyclotron system ...

The sensor probes deployed in the electric fields will cause the distortion in the vicinities, therefore it may significantly affect the accuracy of the measurements in the electric fields. In this paper, we propose a novel approach to separate the electric field distortion due to the spherical sensor probes in a uniform electric field. Moreover, we also investigate the impacts of the spherical...
