Frequency-Agile Antennas for Wireless Communications

Ubiquitous IT services are just beginning to emerge, yet the time is coming when they will truly revolutionize information technology. Based on groundbreaking papers presented at the International Symposium on New Frontiers for Ubiquitous IT Services, this far-reaching resource provides engineers with a detailed look at the technological developments that are blazing the way to a new information age.

During the 1980s the worldwide interest in electromagnetic compatibility (EMC) grew rapidly with the introduction of legislation to control the growing interference problems generated by the increased use of electronic equipment in industry and in the home.

Numerical simulation is essential to electrical engineers working in antenna design, wireless communications, optical systems, and a host of other areas. This new applications-focused book provides engineers with state-of-the-art methods for predicting simulation accuracy, worked-out results for dozens of real-world problems, the latest accuracy-improving techniques, and detailed guidance for all parameters required to optimize numerical simulations.

Advanced Lighting Controls is edited by Craig DiLouie and written for engineers, architects, lighting designers, electrical contractors, distributors, and building owners and managers. Advanced lighting controls, indicated by research as the “next big thing,” are now mandated by the ASHRAE/IES 91.1-1999 energy standard, the basis for all state energy codes in the U.S., and are becoming the norm rather than the exception in new construction

The main reason for the premature breakdown of today’s electronic products (computers, cars, tools, appliances, etc.) is the failure of the components used to build these products. Today professionals are looking for effective ways to minimize the degradation of electronic components to help ensure longer-lasting, more technically sound products and systems.
