This book was released on 2002-08-09 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Challenges facing the implementation of an affordable tunable RF and microwave device technology are discussed in these papers from an April 2002 meeting. Materials issues and devices are examined, with information on new tunable materials, issues of preparation and optimization of bulk and think film properties, material and surface characterization, evaluation of material loss and loss mechanisms, and effects of microstructure. At the device level, phase shifters are discussed and a new device concept for variable true time delay versus phase shift is introduced. At the system level, a paraelectric lens is used to demonstrate electronic beam steering of an antenna. Tidrow is affiliated with the US Army Research Laboratory.
