Compact Size Wireless Power Transfer Using Defected Ground Structures

Compact Size Wireless Power Transfer Using Defected Ground Structures

This book addresses the design challenges in near-field wireless power transfer (WPT) systems, such as high efficiency, compact size, and long transmission range. It presents new low-profile designs for the TX/RX structures using different shapes of defected ground structures (DGS) like (H, semi-H, and spiral-strips DGS). Most near-field WPT systems depend on magnetic resonant coupling (MRC) using 3-D wire loops or helical antennas, which are often bulky. This, in turn, poses technical difficulties in their application in small electronic devices and biomedical implants. To obtain compact structures, printed spiral coils (PSCs) have recently emerged as a candidate for low-profile WPT systems. However, most of the MRC WPT systems that use PSCs have limitations in the maximum achievable efficiency due to the feeding method. Inductive feeding constrains the geometric dimensions of the main transmitting (TX)/receiving (RX) resonators, which do not achieve the maximum achievable unloaded quality factor. This book will be of interest to researchers and professionals working on WPT-related problems.

'Abdu'l-Baha, The Centre of the Covenant of Baha'u'llah was the first comprehensive biography of this 'magnetic figure' and 'perfect Exemplar' of Baha'i life, and remains the foremost source for subsequent accounts. Over 250 pages describe 'Abdu'l-Baha's journey to the West, the places He visited and audiences He addressed, many of those who were privileged to meet Him, and the example He gave in daily life. The ideals He upheld for all are reflected in a wealth of quotations from His talks.

Abdul Baha On Divine Philosophy is a book written by Abdul Baha, the son of the founder of the Baha'i faith, Baha'u'llah. The book was originally published in 1918 and is a collection of Abdul Baha's teachings on the nature of God, the purpose of creation, and the spiritual evolution of humanity. The book is divided into two parts, the first of which focuses on the principles of divine philosophy and the second on the application of these principles to daily life. Throughout the book, Abdul Baha emphasizes the importance of unity, love, and service to others as essential aspects of spiritual growth and fulfillment. The book is a key text in the Baha'i faith and is considered to be a valuable resource for anyone seeking to deepen their understanding of spirituality and the nature of God.This Is A New Release Of The Original 1918 Edition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions, that are true to their original work.
