This study deals with the polarization and depolarization currents of linear/nonlinear double-layered composites, and sets out to explore interface polarization and depolarization characteristics. The linear layer is pure low density polyethylene (LDPE) matrix. The nonlinear barrier layer is prepared by adding nanofillers (ZnO and SiC) to LDPE with different concentrations. Experimental results show...
In this paper, an efficient reciprocity-based algorithm is extended to predict the induced voltage on terminations of a microstrip line and a power divider enclosed in apertured shielding cavities, which are excited by plane wave respectively. The voltage on terminations induced by plane wave of arbitrary incident direction and arbitrary linear polarization can be calculated with minimal simulations,...
The transient characteristics of the interface charges and the electric fields in the nonlinear/linear and nonlinear/nonlinear dielectrics under different amplitudes of dc step voltages and polarity reversal voltages are simulated using the software of Matlab-Simulink. The simulation results show that the interface charges and electric fields of the double-layered dielectrics not only relate with...
Focused by a high numerical-aperture objective in free space, the cylindrical vector beam phase-encoded by vortex phase plate with higher topological charge was capable to generate the doughnut-shaped spot in the vicinity of the focal region. The width of the dark focal spot was manipulated by the phase plate with different topological charge. The relationship between the properties of the focal spot...
