The spin reorientation (SR) phenomenon of the square-lattice antiferromagnets RMnAsO (R = Ce, Nd) was investigated by analyzing the spin-exchange interactions between the rare-earth and the transition ...

We report a method for filtering white light into individual colors using metal−insulator−metal resonators. The resonators are designed to support photonic modes at visible frequencies, and dispersion ...

In this paper, a new control strategy for a HF square-wave inverter is presented. This ballast keeps lamp power harmonics at low levels, regardless of the lamp equivalent load. The proposed ballast, ...
