Key advances in Semiconductor Terahertz (THz) Technology now promises important new applications enabling scientists and engineers to overcome the challenges of accessing the so-called "terahertz gap". This pioneering reference explains the fundamental methods and surveys innovative techniques in the generation, detection and processing of THz waves with solid-state devices, as well as illustrating their potential applications in security and telecommunications, among other fields. With contributions from leading experts, Semiconductor Terahertz Technology: Devices and Systems at Room Temperature Operation comprehensively and systematically covers semiconductor-based room temperature operating sources such as photomixers, THz antennas, radiation concepts and THz propagation as well as room-temperature operating THz detectors. The second part of the book focuses on applications such as the latest photonic and electronic THz systems as well as emerging THz technologies including: whispering gallery resonators, liquid crystals, metamaterials and graphene-based devices. This book will provide support for practicing researchers and professionals and will be an indispensable reference to graduate students in the field of THz technology. Key features: Includes crucial theoretical background sections to photomixers, photoconductive switches and electronic THz generation & detection. Provides an extensive overview of semiconductor-based THz sources and applications. Discusses vital technologies for affordable THz applications. Supports teaching and studying increasingly popular courses on semiconductor THz technology.

A comprehensive, multidisciplinary overview of radio engineering. It should be useful to electrical engineers working in wireless communications and a host of other application areas, including sensors, navigation and radar. The text teaches professionals important techniques for the generation, control, detection and utilization of radio waves, and provides detailed guidance in radio link, amplifier and antenna design.

Teos käsittelee radiotekniikkaa eli radioaaltojen synnyttämiseen, hallitsemiseen, havaitsemiseen ja hyödyntämiseen tarvittavaa tekniikkaa. Radiotekniikan tärkeimmät sovellusalueet ovat tietoliikenne, radionavigointi sekä tutka ja muut anturit. Radioaaltoja syntyy paitsi ihmisen rakentamissa radiolaitteissa myös monissa luonnon ilmiöissä. Tämä mahdollistaa radiotekniikan käytön myös ympäristön seurannassa ja avaruuden tutkimuksessa. Teos soveltuu oppikirjaksi elektroniikkaa ja tietoliikennetekniikkaa yliopistoissa ja korkeakouluissa opiskeleville ja täydennyskoulutusmateriaaliksi radiotekniikan kanssa tekemisiin joutuville muille ammattilaisille.
