Download or read book Electromagnetic Interference Measurement Methods - Shielded Enclosure written by William R. Free and published by . This book was released on 1967 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the period covered by this report, investigations of techniques and procedures for making radiation measurements in shielded enclosures which can be correlated with open-field measurements have continued. The primary objective of this program is to develop a capability for determining the case radiation and susceptibility characteristics of U.S. Army communication equipments in the controlled environments of shielded enclosures. A microwave hooded antenna capable of making the desired measurements in a shielded enclosure over the frequency range from 1 to 12 GHz has been developed and evaluated. Techniques for calibrating this probe antenna have been investigated during this period and are described in detail. A UHF hooded antenna, for use over the frequency range from 200 to 1500 MHz, has also been developed. The evaluation of this probe antenna has continued during this period and the results obtained to date are presented. Theoretical and experimental investigations of the field distribution within a shielded enclosure at low frequencies are discussed. (Author).

This book was released on 2022-11-08 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rapid developments in microchips, mobile communication and satellite communication, electromagnetic interference (EMI) or Radio Frequency Interference (RFI) has received significant attention to ensure high performance of electronic items and to avoid any adverse effect on human health. EMI is one of the main factors that weaken electronic system performance and is considered as a modern form of environmental pollution. Many efforts have been made to reduce EMI, including industrial regulations and R&D funding.The expansion of the IT industry has promoted the development of microwave absorbing materials (MAMs) and EMI shielding materials to improve the resistance of smart devices to EMI. This book presents a comprehensive review of the recent developments in EMI shielding and the design of microwave absorbing materials. Chapters cover the basic mechanism of shielding and radiation absorption, measurement procedures, factors affecting the shielding and different materials for shielding and absorption (e.g. MWCNT, conjugated polymers, graphene, MXene based hybrid materials, Carbon foam, graphene based thermoplastic polyurethane nanocomposites, carbon-carbon composites, nano ferrite composites and conducting Ferro fluids). An analysis of EMI shielding using fillers composed of different materials is also presented. In addition, key issues and current challenges to achieve better shielding and absorption performance for various materials are explained, giving the readers a broader perspective of the subject. The book is suitable as a detailed reference for students in electronics engineering, materials science and other technical courses, and professionals working on materials for designing EMI shielding mechanisms.

Book Synopsis Electromagnetic Interference Measurement Methodology, Communication Equipment by : William R. Free
Download or read book Electromagnetic Interference Measurement Methodology, Communication Equipment written by William R. Free and published by . This book was released on 1968 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this reporting period, primary emphasis has been directed toward the development of techniques for measuring radiated interference and susceptibility in shielded enclosures over the frequency range from 20 MHz to 200 MHz. A theory has been developed to explain the presence of coupling nulls in the near-field of radiating sources in shielded enclosures at low frequencies (below 100 MHz). If this theory can be validated, additional approaches to the solution of the measurement problems in the 20 to 200 MHz frequency range will be available. An experimental study program to determine the optimum length for the hood of a hooded antenna was initiated during this period. Preliminary results from this study indicate that it may be possible to obtain an essentially constant beamwidth over a frequency bandwidth of greater than 3:1. (Author).
