"Provides detailed explanations of basic theory and applied theory for understanding EM-wave absorbers -Discusses the material constant measurement methods of EM-wave absorption characteristics that are necessary for designing the EM-wave absorber -Includes examples of EM-wave absorber configurations In recent years, along with increases in various kinds of demands on communication systems, the communication environment has become more and more complicated. As a result, the introduction of EM-wave absorbers is required in each technical field, especially from the viewpoint of preventing interference and mutual interaction. Demands for various EM-wave absorbers are rapidly increasing along with the recent trends towards complicated electromagnetic environments and development of higher-frequency communication equipment. Further, the rapid progress of recent artificial intelligence (AI) technology is now remarkable. With its rapid progress the need of electrical controllable EM-wave absorbers is being realized"-- Provided by publisher.
