Wireless power transfer via Subterahertz-wave

Wireless Power Transfer System

This paper presents a survey of recent wireless power transfer systems. The issue of wireless power transfer is to achieve a highly efficient system with small positioning errors of the facilities setting. Several theories have been presented to obtain precise system design. This paper presents a summary of design theory for short range power transfer systems and detailed formulations based on ...

Review of terahertz and subterahertz wireless communications

Wireless Transfer of Electric Power

In this dissertation, I describe the design and construction of a system which can transfer electric power wirelessly. This is accomplished using inductive, near-field, non-radiative coupling between self-resonant copper helices. In our first experiment, we transfered 60W of power over a distance of 2m with 45% efficiency. In our second experiment, we designed a system which can transfer power ...

Design and Testing of Millimeter-Wave/Subterahertz Circuits and Systems

h WITH THIS LAST D&T issue of 2014, we welcome our readers to a topic we have yet to cover: millimeter wave (mm-wave) and subterahertz (sub-THz) circuits. We are excited to bring this focused and timely issue before you, with the goal of highlighting some of the most trailblazing solutions to contemporary challenges in the design and test of mm-wave and sub-THz circuits/systems. The wide applic...

Wireless Power Transfer System via Magnetic Resonant Coupling at Fixed Resonance Frequency ―Power Transfer System Based on Impedance Matching

To increase the usage of electric vehicles (EV), a safe and convenient method to charge the vehicles is essential. Recently, an efficient mid range wireless power transfer that uses magnetic resonant coupling, WiTricity, was proposed, and has received much attention due to its practical range and efficiency. Studies show that the resonance frequency of the antennas changes as the gap between th...
