With the fast development of information storage, exploiting new concepts for dense, fast, and non-volatile random access memory with reduced energy consumption is a significant and challenging task. To realize this goal, electric-field control of magnetism is crucial. In this regard, multiferroic materials are important and have attracted much attention due to their interesting new physics and potentials...
Summary form only given. Terahertz radiation, which ranges from 0.1 THz to 10 THz, has received substantial interests in recent years. The conventional vacuum electronics technology has the potential to supply high enough powers to underpin many exciting and emerging THz applications. Klystrons have been designed to generate THz radiation. This vacuum device requires a very small sized RF circuit...
The basic operation principle of microwave oscillators, such as magnetrons, is based on the motion of electrons under a combined influence of electric and magnetic fields. In such process, the DC energy is converted into the RF energy via the interaction process between the electrons and the surrounding electromagnetic field. This nonlinear process provides sufficient conditions in generating rather...
This paper introduces permittivity shielding. Permittivity shielding enables the measurement of voltage with very few electric field sensors. Voltage sensor designs using permittivity shielding can exploit existing optical sensor technology without the need for the expensive and potentially hazardous insulation found in many modem optical voltage transducers. Numerical simulations demonstrate that...
