This paper analyses and designs a kind of wireless power transmission system via near field resonant coupling. It introduces the wireless power transmission technology, and combination of traditional inductive coupling and resonance. The project consists of modeling and construction of the hardware to prove the feasibility of wireless power transmission using near field resonant coupling. The h...
As the input rf power to a helicon plasma is increased there is a discontinuous increase in the density which is identified with a change from a capacitive to an inductive/wave coupling to the plasma. The radial distribution of the density is much narrower in the inductive ~high! mode than in the capacitive ~low! mode. Although the time average plasma potential (Vp) decreases markedly at this m...
We investigate combined effects of spin-orbit coupling and magnetic field in carbon nanotubes containing one or more bends along their length. We show how bends can be used to provide electrical control of confined spins, while spins confined in straight segments remain insensitive to electric fields. Device geometries that allow general rotation of single spins are presented and analyzed. In a...
The exact location of a single dopant atom in a nanostructure can influence or fully determine the functionality of highly scaled transistors or spin-based devices. We demonstrate here a noninvasive spatial metrology technique, based on the microscopic modeling of three electrical measurements on a single-atom (phosphorus in silicon) spin qubit device: hyperfine coupling, ground state energy, a...
Short, medium, and long on-chip interconnections having linewidths of 0.45–52 m are analyzed in a five-metallayer structure. We study capacitive coupling for short lines, inductive coupling for medium-length lines, inductance and resistance of the current return path in the power buses, and line resistive losses for the global wiring. Design guidelines and technology changes are proposed to ach...
Variable angle spinning (VAS) experiments can be used to measure long-range dipolar couplings and provide structural information about molecules in oriented media. We present a probe design for this type of experiment using a contactless resonator. In this circuit, RF power is transmitted wirelessly via coaxial capacitive coupling where the coupling efficiency is improved by replacing the ordin...
This paper presents a 600kHz MEMS bandpass filter implemented using electrical coupling of single crystal silicon HARPSS micromechanical resonators. Passive and active filter synthesis approaches based on electrical coupling of capacitive MEMS resonators are introduced and discussed. A third order passive bandpass filter at the center frequency of 600kHz with a bandwidth of 125Hz, a stopband re...
