An in-depth look at the state-of-the-art in microwave filter design, implementation, and optimization Thoroughly revised and expanded, this second edition of the popular reference addresses the many important advances that have taken place in the field since the publication of the first edition and includes new chapters on Multiband Filters, Tunable Filters and a chapter devoted to Practical Considerations and Examples. One of the chief constraints in the evolution of wireless communication systems is the scarcity of the available frequency spectrum, thus making frequency spectrum a primary resource to be judiciously shared and optimally utilized. This fundamental limitation, along with atmospheric conditions and interference have long been drivers of intense research and development in the fields of signal processing and filter networks, the two technologies that govern the information capacity of a given frequency spectrum. Written by distinguished experts with a combined century of industrial and academic experience in the field, Microwave Filters for Communication Systems: * Provides a coherent, accessible description of system requirements and constraints for microwave filters * Covers fundamental considerations in the theory and design of microwave filters and the use of EM techniques to analyze and optimize filter structures * Chapters on Multiband Filters and Tunable Filters address the new markets emerging for wireless communication systems and flexible satellite payloads and * A chapter devoted to real-world examples and exercises that allow readers to test and fine-tune their grasp of the material covered in various chapters, in effect it provides the roadmap to develop a software laboratory, to analyze, design, and perform system level tradeoffs including EM based tolerance and sensitivity analysis for microwave filters and multiplexers for practical applications. Microwave Filters for Communication Systems provides students and practitioners alike with a solid grounding in the theoretical underpinnings of practical microwave filter and its physical realization using state-of-the-art EM-based techniques.

For over a decade and with the best of intentions, the U.K. government has spent millions attempting, but largely failing, to improve personal, social and educational outcomes for children and young people in public care. In this book, the authors explain why the problems of this highly vulnerable group have resisted such effort, energy and expenditure and go on to show how achieving positive outcomes for children in care is possible when the root causes of failure are tackled.

Topic covered include:

- The power of parenting

- The impact of parental rejection on emotional development

- Support for the adaptive emotional development of children and young people

- Practical advice on introducing the 'Authentic Warmth' approach into existing childcare organisations

- Future issues in childcare

This book is essential reading for carers, commissioners, policymakers, support professionals, designated teachers and students of social work.
