Time-Varying Wireless Power Transfer Systems for Improving Efficiency
X. Wang, I. Krois, N. Ha-Van +4
Conventional wireless power transfer systems are linear and time-invariant, which sets fundamental limitations on their performance, including a tradeoff between transfer efficienc…
Effective Mid-Range Wireless Power Transfer with Compensated Radiation Loss
N. Ha-Van, C. R. Simovski, F. S. Cuesta +2
In conventional inductive wireless power devices, the energy is transferred via only reactive near fields, which is equivalent to non-radiative Förster energy transfer in optics. R…
Antenna bandwidth engineering through time-varying resistance
M. H. Mostafa, N. Ha-Van, P. Jayathurathnage +3
Operational bandwidth of resonant circuits is limited by the resonator's size, which is known as the Chu limit. This limit restricts miniaturization of antennas, as the antenna ban…
Up-And-Coming Physical Concepts of Wireless Power Transfer
Mingzhao Song, Prasad Jayathurathnage, Esmaeel Zanganeh +7
The rapid development of chargeable devices has caused a great deal of interest in efficient and stable wireless power transfer (WPT) solutions. Most conventional WPT technologies…
Time-varying components for enhancing wireless transfer of power and information
Prasad Jayathurathnage, Fu Liu, Mohammad S. Mirmoosa +3
Temporal modulation of components of electromagnetic systems provides an exceptional opportunity to engineer the response of those systems in a desired fashion, both in the time an…
Active Metasurfaces as a Platform for Capacitive Wireless Power Transfer Supporting Multiple Receivers
Fu Liu, Prasad Jayathurathnage, Sergei A. Tretyakov
As wireless power transfer (WPT) repeaters, metasurfaces can enhance field coupling, improving the WPT operation. In this paper, we show that metasurfaces can also be used as trans…
Automatic Receiver Tracking and Power Channeling for Multi-Transmitter Wireless Power Transfer
Prasad Jayathurathnage, Xiaojie Dang, Sergei A. Tretyakov +1
Free positioning of receivers is one of the key requirements for many wireless power transfer (WPT) applications, required from the end-user point of view. However, realization of…
Omnidirectional Wireless Power Transfer with Automatic Power Flow Control
Prasad Jayathurathnage, Xiaojie Dang, Fu Liu +2
We present an omnidirectional wireless power transfer (WPT) system capable of automatic power flow control using three orthogonal transmitter (Tx)-repeater (Rp) pairs. The power dr…
Pulsed Self-Oscillating Nonlinear Systems for Robust Wireless Power Transfer
Fu Liu, Bhakti Chowkwale, Prasad Jayathurathnage +1
While wired-power-transfer devices ensure robust power delivery even if the receiver position or load impedance changes, achieving the robustness of wireless power transfer (WPT) i…
