Abstract
In this letter, we propose a wireless power transfer (WPT) system with conformal receivers based on parity-time (PT) symmetry. The transmitter is constructed by a negative resistor powered parallel LC circuit, including a planar transmitting coil. The two receivers are both of parallel LCR topology with flexible coils as the inductance. The transmission characteristics of the system are analyzed and verified under different conformal conditions of the two receiving coils. The theoretical analyses and experimental results show that whether the two receiving coils are planar or cylindrical, the PT symmetric state can be achieved and robust transmission features can be obtained in the strong coupling region. The proposed WPT system can provide references for practical wireless charging platforms when deformations of electronic devices occur and multi devices need to be charged.
期刊介绍：
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
