Abstract

This work has arisen out of the strong demand for a superior power-added efficiency (PAE) of AlGaN/GaN high electron mobility transistor (HEMT) high-power amplifiers (HPAs) that are part of any advanced wireless multifunctional RF-system with limited prime energy. Different concepts and approaches on device and design level for PAE improvements are analyzed, e.g. structural and layout changes of the GaN transistor and advanced circuit design techniques for PAE improvements of GaN HEMT HPAs.

Abstract

Die 1972 von den Frankfurter Slavisten Olexa Horbatsch und Gerd Freidhof begründete Reihe Specimina philologiae Slavicae wird heute von Holger Kuße (Dresden), Peter Kosta (Potsdam), Beatrix Kreß (Hildesheim), Franz Schindler (Gießen), Barbara Sonnenhauser (Zürich) und Nadine Thielemann (Wien) herausgeben. In der Reihe erscheinen Monographien, Sammelbände und Lehrbücher zu allen Gebieten der Slavistik, der Sprach-, der Literatur- und der Kulturwissenschaft. In der Sprachwissenschaft erscheinen sowohl sprachhistorische als auch innovative Arbeiten zur Pragmatik und Semantik, zu slavischen Kleinsprachen und zur Diskurslinguistik. In der Literatur- und Kulturwissenschaft gehört zu den besonderen Interessensgebieten die Russische Philosophie.

Abstract

The subject of this work is the design, implementation and first results of the ""CERN Resonant WISP Search"" (CROWS), which probes the existence of Axion Like Particles and Hidden Sector Photons (HSPs) using microwave techniques. By exploiting low loss cavity resonators, multiple layers of electromagnetic shielding and a micro-Hz bandwidth detection scheme, new exclusion limits could be set. For HSPs, sensitivity was improved by a factor of ~7 compared to previous laboratory experiments.

Abstract

With the growing interest in the use of technology in daily life, the potential for using wearable wireless devices across multiple segments, e.g., healthcare, sports, child monitoring, military, emergency, consumer electronics, etc., is rapidly increasing. Multibillion wearable sensors are predicted to be in use by 2025, with over 30% of them being new types of sensors that are only beginning to emerge. This book will focus on wireless wearable and implantable systems, flexible textile-based electronics, bio-electromagnetics, antennas and propagation, radio frequency (RF) circuits, sensors, security of wearables and implantable systems, nano-bio communication, and electromagnetic sensing

Abstract

The Special Edition 'Compounds with Polar Metallic Bonding' is a collection of eight original research reports presenting a broad variety of chemical systems, analytical methods, preparative pathways and theoretical descriptions of bonding situations, with the common aim of understanding the complex interplay of conduction electrons in intermetallic compounds that possess different types of dipoles. Coulombic dipoles introduced by electronegativity differences, electric or magnetic dipoles, polarity induced by symmetry reduction—all the possible facets of the term 'polarity'—can be observed in polar intermetallic phases and have their own and, in most cases, unique consequences on the physical and chemical behaviour. Elucidation of the structure–property relationships in compounds with polar metallic bonding is a modern and growing scientific field which combines solid state physics, preparative chemistry, metallurgy, modern analytic methods, crystallography, theoretical calculations of the electronic state and many more disciplines.
