Abstract
Technology for wireless power transfer (WPT) has gained more importance in the
contemporary world. The upsurge spike can be a result of the WPT system's ability to power
devices without the use of traditional connections. In particular, near-field WPTs have a wide
range of applications, including wireless sensors, IoT, biomedical implants, RFID, and consumer
electronics. It is essential to emphasize that the WPT system can be realized in a number of ways,
one of which is a defected ground structure technique. This approach is well-established for its
simple design process and compact system. Despite this recently developed DGS-based WPTs
demonstrate poor performance, in other words, low power transfer efficiency in practical
validations. The inevitable factors, such as imperfections of lumped elements, the in-house
fabrication, and energy losses during transfer, have an impact on the experimental results.
Therefore, various performance enhancement strategies have to be considered to realize the
compact and efficient WPT system. In this regard, one of the promising methods for improving
WPT operation is the use of metamaterial, which is an artificial material with unique
electromagnetic features. As a result, this thesis work focuses on the development of compact and
efficient WPTs applicable to various fields and on performance enhancement strategies based on
metamaterial utilization
