Indigenous church leadership is a new phenomenon in North Africa. Until recently, non-Muslim background believers were the only leaders of churches in this region. With the current growth of national churches there are increasingly more leaders from a Muslim background leading to a diverse range of leadership styles. This publication, a first of its kind to specifically explore church leadership in North Africa, investigates common values, beliefs and cultures among church leaders. Using four identified leadership styles the author further expands by looking at the impact they have on congregations, society and the future development of church leaders in the region.
Most mission studies have focused on the work of Western missionaries going to Majority World countries, with few examining indigenous churches and their relationship with Western mission agencies in practicing mission. This book is a historical study of the relationship between the Evangelical Church in Egypt and the American Presbyterian Mission. Wahba covers from when the missionary work began in 1854 until after the departure of the Mission from Egypt in 1967, and the transfer of all the work to the Egyptian Evangelical Church. Tracing the mission work of Egyptians within Egypt and neighbouring Sudan, Wahba analyses the impact that the relationship with the American Mission had and how it determined the indigenous Church’s practice and perspective of mission.
“ Book Endorsement” To write about this book brings me honor and joy. For these recollections clearly show the greatness, ability, love, and protection of the Lord. To Him be the glory. It also shows the greatness of what Engineer Samy Hanna Ibrahim did in the October 1973 war. After he himself ascended it, he penetrated the high earth wall and crossed the Egyptian forces assigned to his crossing access from the west of the Suez Canal to the eastern shore. Thus, he contributed to the victory of a war, which returned Sinai to Egypt. That return changed Egypt for the better after its setback in June 1967. Dr. Mufeed Ibrahim Said, retired professor of surgery and former chair of the departm...
This comprehensive resource provides a thorough introduction to the principles of electronic circuits operating in the radio, microwave, and millimeter-wave frequency ranges. The book highlights the fundamental physical laws of classical electromagnetics using a foundation of Maxwell’s equations to give insight into the operating principles of circuit elements of all kinds, from lumped elements to transmission lines, waveguides, optical fibers, and quasi-optical structures. Standard passive system components like filters, splitters, couplers, hybrids, baluns, and antennas are explained to acclimate the reader to considering multiple technological solutions for common design problems. A bas...
This authoritative new resource provides an overview and introduction to working with RF, microwave, and high frequency components. From transmission lines, antennas, millimeter waves, ferrites, hybrids, power dividers and filters, this book focuses on practical, time-to-market issues to help with projects in the field. Keeping mathematics to a minimum, this comprehensive volume is packed with over 700 illustrations that help clarify key concepts. The reader will gain an in-depth understanding of the special characteristics exploited in microwave and high frequency design. The book is also used in industrial training courses.
All model parameters are fundamentally coupled together, so that directly measured individual parameters, although widely used and accepted, may initially only serve as good estimates. This comprehensive resource presents all aspects concerning the modeling of semiconductor field-effect device parameters based on gallium-arsenide (GaAs) and gallium nitride (GaN) technology. Metal-semiconductor field-effect transistors (MESFETs), high electron mobility transistors (HEMTs) and heterojunction bipolar transistors (HBTs), their structures and functions, and existing transistor models are also classified. The Shockley model is presented in order to give insight into semiconductor field-effect tran...
This authoritative resource offers professionals and students valuable assistance with their work and studies involving microwave circuit analysis and design. Readers gain a thorough understanding of the properties of planar transmission lines for integrated circuits. Moreover, this practical book presents matrix and computer-aided methods for analysis and design of circuit components. Engineers find in-depth details on input, output, and interstage networks, as well as coverage of stability, noise, and signal distortion.
Written by an internationally recognized as an expert on the subject of microwave (MW) tubes, this book presents and describes the many types of microwave tubes, and despite competition from solid-state devices (those using GaN, SiC, et cetera), which continue to be used widely and find new applications in defense, communications, medical, and industrial drying. Helix traveling wave tubes (TWTs), as well as coupled cavity TWTs are covered. Klystrons, and how they work, are described, along with the physics behind it and examples of devices and their uses. Vacuum electron devices are explained in detail and examines the harsh environment that must exist in tubes if they are to operate properl...
Substrate Integrated Suspended Line Circuits and Systems provides a systematic overview of the new transmission line - the substrate-integrated suspension line (SISL). It details the fundamentals and classical application examples of the SISL. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems are systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideal for researchers, engineers, scientists, scholars, educators, and students. Since transmission line is a fundamental component of microwave and mm-wave circuits, the properties of a transmission line, ...
This unique first-of-its-kind resource provides practical coverage of the design and implementation of frequency measurement receivers, which aid in identifying unknown signals. The technologies used in frequency measurement interferometry-based on-delay lines and filters are explored in this book. Practitioners also find concrete examples of microwave photonics implementations. The designs and concepts that cover conventional photonic instantaneous frequency measurement (IFM) circuits are explained. This book provides details on new designs for microwave photonic circuits and reconfigurable frequency measurement (RFM) circuits using diodes and MicroElectroMechanical Systems (MEMS). This boo...
