In diesem dringend notwendigen Referenzwerk untersuchen die Autoren, renommierte Experten des Fachgebiets, das Prinzip des Elektromagnetismus nach Maxwell und beschreiben die Eigenschaften einer Antenne im Frequenzbereich. Beleuchtet werden ebenfalls die Ausbreitungsverluste in Drahtlosnetzen sowie Ultrabreitband-Antennen und die Mechanismen der Breitbandübertragung von elektrischem Strom und Daten. Der Inhalt im Überblick:- Erörtert die Schwächen von MIMO-System aus theoretischer und praktischer Sicht.- Zeigt, wie sich Basisstationsantennen so einsetzen lassen, dass sie effizienter arbeiten.- Validiert das Prinzip und die theoretische Analyse der elektromagnetischen Ausbreitung in der drahtlosen Kommunikation.- Zeigt Ergebnisse aus Experimenten, die in der Mathematik und Physik verankert sind.

New method for the characterization of electromagnetic wave dynamicsModern Characterization of Electromagnetic Systems introduces a new method of characterizing electromagnetic wave dynamics and measurements based on modern computational and digital signal processing techniques. The techniques are described in terms of both principle and practice, so readers understand what they can achieve by utilizing them.Additionally, modern signal processing algorithms are introduced in order to enhance the resolution and extract information from electromagnetic systems, including where it is not currently possible. For example, the author addresses the generation of non-minimum phase or transient response when given amplitude-only data.* Presents modern computational concepts in electromagnetic system characterization* Describes a solution to the generation of non-minimum phase from amplitude-only data* Covers model-based parameter estimation and planar near-field to far-field transformation as well as spherical near-field to far-field transformationModern Characterization of Electromagnetic Systems is ideal for graduate students, researchers, and professionals working in the area of antenna measurement and design. It introduces and explains a new process related to their work efforts and studies.
