This book describes a new concept in analyzing RF/Microwave circuits, which includes RF/Microwave antennas. The analysis is based on nonlinear dynamics and chaos models and shows comprehensive benefits and results. All conceptual RF microwave circuits and antennas are innovative and can be broadly implemented in engineering applications. The presentation fills the gap of analytical methods for microwave RF antennas and circuit's analysis, concrete examples, and geometric examples. The microwave RF antennas and circuits analysis is developed systematically, starting with basic microwave RF circuits and antennas differential equations and their bifurcations, followed by fixed points analysis, ...
Benjamin Elman describes how education, examinations, and civil service fostered the world's first professional class based on demonstrated knowledge. Chinese civil examinations, a piece of social engineering worked out over centuries, prefigured the regime of meritocratic exams that undergirds higher education around the globe today.
Essentials of RF Front-end Design and Testing Highly comprehensive text delivering the RF system essentials required to understand, develop, and evaluate the performance of RF wireless systems Essentials of RF Front-end Design and Testing: A Practical Guide for Wireless Systems is a system-oriented book which provides several wireless communication disciplines in one volume. The book covers a wide range of topics, including antenna fundamentals, phased array antenna and MIMOs that are crucial for the latest 5G mmWave and future 6G wireless systems, high-frequency transmission lines, RF building blocks that are necessary to understand how various RF subsystems are interrelated and implemented...
This book explores the transformation of the Chinese capital both socially and physically during the final decades of the twentieth century.
This Brief introduces the wireless spectrum market and discusses the current research for spectrum auctions. It covers the unique properties of spectrum auction, such as interference relationship, reusability, divisibility, composite effect and marginal effect, while also proposing how to build economic incentives into the network architecture and protocols in order to optimize the efficiency of wireless systems. Three scenarios for designing new auctions are demonstrated. First, a truthful double auction scheme for spectrum trading considering both the heterogeneous propagation properties of channels and spatial reuse is proposed. In the second scenario, a framework is designed to enable spectrum group secondary users with a limited budget. Finally, a flexible auction is created enabling operators to purchase the right amounts of spectrum at the right prices according to their users’ dynamic demands. Both concise and comprehensive, Auction Design for the Wireless Spectrum Market is suited for professionals and researchers working with wireless communications and networks. It is also a useful tool for advanced-level students interested in spectrum and networking issues.
