This book focuses on the status quo and current trends concerning ethnic issues in China, and seeks to promote the equitable and harmonious development of Chinese and other nationalities around the world. Drawing on representative empirical studies and case studies, it describes the spatial structure and evolution of China’s populace, and analyzes the distribution of and legislation on its spatial development, which has been conducive to the scientific formulation of national population policies. After assessing the development of China’s populace, the book analyzes the future prospects with regard to achieving the goal of a prosperous society and balancing the population in a comprehensive way; puts forward some constructive suggestions on the modernization of the populace; and constructs a new knowledge system for national development with Chinese characteristics. The book combines qualitative and quantitative analysis and employs empirical, speculative, comparative, and comprehensive methods to make full use of modern science and technology, so as to promote ethnological research into a broader development path. Its goal is to objectively evaluate the development of the Chinese populace and provide objective facts and data to support those readers who are interested in its nature and evolution.
A comprehensive guide to antenna design, manufacturing processes, antenna integration, and packaging Antenna-in-Package Technology and Applications contains an introduction to the history of AiP technology. It explores antennas and packages, thermal analysis and design, as well as measurement setups and methods for AiP technology. The authors—well-known experts on the topic—explain why microstrip patch antennas are the most popular and describe the myriad constraints of packaging, such as electrical performance, thermo-mechanical reliability, compactness, manufacturability, and cost. The book includes information on how the choice of interconnects is governed by JEDEC for automatic assembly and describes low-temperature co-fired ceramic, high-density interconnects, fan-out wafer level packaging–based AiP, and 3D-printing-based AiP. The book includes a detailed discussion of the surface laminar circuit–based AiP designs for large-scale mm-wave phased arrays for 94-GHz imagers and 28-GHz 5G New Radios. Additionally, the book includes information on 3D AiP for sensor nodes, near-field wireless power transfer, and IoT applications. This important book: • Includes a brief history of antenna-in-package technology • Describes package structures widely used in AiP, such as ball grid array (BGA) and quad flat no-leads (QFN) • Explores the concepts, materials and processes, designs, and verifications with special consideration for excellent electrical, mechanical, and thermal performance Written for students in electrical engineering, professors, researchers, and RF engineers, Antenna-in-Package Technology and Applications offers a guide to material selection for antennas and packages, antenna design with manufacturing processes and packaging constraints, antenna integration, and packaging.
