Wireless power transfer (WPT) has the potential to revolutionize how we power electronics, vehicles, and infrastructure. This paper provides a comprehensive review of past WPT research, assessing its current progress and future prospects. Using a descriptive methodology, it consolidates insights from key studies on WPT's history, principles, and state-of-the-art technologies. The review highlights significant advancements in short-range inductive and resonant coupling, particularly for consumer devices and electric vehicles. However, challenges persist in achieving high efficiency and safety over longer distances, particularly with microwave and laser transmission. Concerns about electromagnetic exposure and the lack of standardization hinder widespread adoption. Future research should focus on emerging approaches such as metamaterials, distributed lasers, and simultaneous wireless data and power transfer. Breakthroughs in atmospheric beaming and harvesting energy from biological sources could further expand possibilities. A strategic roadmap integrating renewable energy is recommended to fully exploit WPT's potential across industries.
... Wireless power transmission (WPT) is a method of transferring electrical energy from a source to an electrical load without an electrical wire (conductor). The concept of wireless power transmission was introduced by Nikola Tesla in 1890 [1]. However, the implementation of WPT technology has only been realized recently. ...
Wireless power transmission (WPT) is commonly used today in many important daily applications, such as electric vehicles, mobile phones, and implanted medical devices. The transmitter and receiver coils are essential elements in the WPT system, and the coupling coefficient between these coils plays an important role in increasing the power transfer efficiency. In this work, we introduce a new approach to optimizing the coupling coefficient between the transmitter and the receiver coils by changing the geometries and locations of the coil turns. In the optimization process, the geometry of the turns varies from a rhombus to a circular and then a rectangular shape according to a quasi-elliptical parameter value. The Neuman formula is used to calculate the self-inductance, mutual inductance, and coupling coefficient for each specific geometry and turn location. The configuration with the highest coupling coefficient is then selected at the end of the optimization process. The final WPT coils are tested and verified using Ansys software through electromagnetic and AC analysis simulations. The results show that the new approach could achieve smooth and easily manufacturable coils with higher coupling coefficients, thereby increasing the power transfer efficiency of WPT.

Wireless power transfer (WPT) using inductive and resonant coupling has been widely explored in recent years for ease and safety over conventional cable charging systems. The efficiency of WPT systems is reducing drastically due to an increase in air-gaps and misalignment between transmitter (Tx) and receiver (Rx). Many circuit topologies have been analyzed to improve the efficiency of WPT system based on symmetrical coils. However, the circuit topologies have not been studied widely for unsymmetrical coils. This paper presents the investigation of two fundamental topologies i.e. Series-Series (SS) and Series-Parallel (SP) for unsymmetrical coils as well as symmetrical coils. Theoretical analysis of both the compensation topologies have been accomplished, then modeling of both the topologies have been done using two different combination of circular coils. In first case, two similar size coils have been designed and in second case transmitter coil of higher dimensions than receiver coil is designed. The efficiency of the system has been analyzed at multiple distances in both cases by integrating coil structure with the circuit. The overall result show that when Tx is bigger than Rx, the SP topology gives better efficiency than SS counterpart.

Transportation is considered as the largest contributor to greenhouse gas emissions. Recently, many European countries and the World Health organization (WHO) have passed laws to reduce road vehicles emissions, which are responsible for 60.7% of European road transport air pollution. The electrification of vehicles required various charging infrastructure options. One of the state-of-the-art technologies is dynamic wireless charging systems (to deliver energy to the EV in motion). Thus, this paper summarizes distinct static and dynamic wireless charging technologies for electric vehicles. Analyzing different wireless power transfers and their limitations shows that the static wireless charging stations in house garages or open parking lots and dynamic charging infrastructures in smart roads or highway-charging lanes will be promising solutions in the near future to make electric vehicle charging easier or without making stops for recharging.
