It is aimed at electrical and electronic engineers, RF and microwave engineers, students and researchers in physics, and will also greatly benefit all engineers who have had no formal instruction in nonlinear dynamics, but who now desire to bridge the gap between innovative microwave RF circuits and antennas and advanced mathematical analysis methods.

Microwave Radiation of the Ocean-Atmosphere

by Alexander Grankov Alexander Milshin

The book describes different approaches to the analysis of heat and dynamic processes in the ocean-atmosphere interface with satellite passive radiometric observations of microwaves. It examines the feasibility of determining synoptic, seasonal and year-to-year variations of sensible, latent heat and momentum fluxes to a useful accuracy using the DMSP SSM/I data directly from the measured brightness temperatures. In addition, the text considers the parameters of the ocean surface and the near surface atmosphere as they relate to the processes of the ocean-atmosphere heat and dynamic interaction. These processes can be analyzed from satellites using a variety of methods, including comparison of data of synchronous satellite passive microwave radiometric and direct oceanographic and meteorological measurements, and the modeling of their variations and analysis of interrelations at different time scales.

Microwave Radiometry and Remote Sensing of the Earth's Surface and Atmosphere

by P. Pampaloni S. Paloscia

This book contains a selection of refereed papers presented at the 6 Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment held in Florence, Italy on March 15-18, 1999. Over the last two decades, passive microwave remote sensing has made considerable progress, and has achieved significant results in the study of the Earth's surface and atmosphere. Many years of observations with ground-based and satellite-borne sensors have made an important contribution to improving our knowledge of many geophysical processes of the Earth's environment and of global changes. The evolution in microwave radiometers aboard satellites has increased steadily over recent years. At the same time, many investigations have been carried out both to improve the algorithms for the retrieval of geophysical parameters and to develop new technologies. The book is divided into four main sections: three of these are devoted to the observation of the Earth's surface and atmosphere, and the fourth, to future missions and new technologies. The first section deals with the study of sea and land surfaces, and reports recent advances in remote sensing of ocean wind, sea ice, soil moisture and vegetation biomass, including electromagnetic modelling and the assimilation of radiometric data in models of land surface processes. The following two sections are devoted to the measurement of atmospheric quantities which are of fundamental importance in climatology and meteorology, and, since they influence radio-wave propagation, they also impact on several other fields, including geodesy, navigational satellite and radioastronomy. The last section presents an overview of new technologies and plans for future missions.

Microwave and Millimetre-Wave Design for Wireless Communications

by Ian Robertson Mitchai Chongcheawchamnan Nutapong Somjit

This book describes a full range of contemporary techniques for the design of transmitters and receivers for communications systems operating in the range from 1 through to 300 GHz. In this frequency range there is a wide range of technologies that need to be employed, with silicon ICs at the core but, compared with other electronics systems, a much greater use of more specialist devices and components for high performance - for example, high Q-factor/low loss and good power efficiency. Many text books do, of course, cover these topics but what makes this book timely is the rapid adoption of millimetre-waves (frequencies from 30 to 300 GHz) for a wide range of consumer applications such as wireless high definition TV, "5G" Gigabit mobile internet systems and automotive radars. It has taken many years to develop low-cost technologies for suitable transmitters and receivers, so previously these frequencies have been employed only in expensive military and space applications. The book will cover these modern technologies, with the follow topics covered; transmitters and receivers, lumped element filters, tranmission lines and S-parameters, RF MEMS, RFICs and MMICs, and many others. In addition, the book includes extensive line diagrams to illustrate circuit diagrams and block diagrams of systems, including diagrams and photographs showing how circuits are implemented practically. Furthermore, case studies are also included to explain the salient features of a range of important wireless communications systems. The book is accompanied with suitable design examples and exercises based on the Advanced Design System - the industry leading CAD tool for wireless design. More importantly, the authors have been working with Agilent Technologies on a learning & teaching initiative (www.awrcorp.com/professors-in-partnership), which is designed to promote access to ongoing microwave and RF educational content that enhances and promotes AWR software solutions through ebooks and textbooks. In parallel, Agilent have recently started to offer access to this software to students without charge, providing universities have a site license. Students are able to download the software and use it on their own devices. This advanced text is therefore developed with the partnership in mind; to enable the reader to develop and their own circuits and subsystems using modern software tools and test equipment.
