John Wiley & Sons Inc Electromagnetic Fields in Cavities: Deterministic and Statistical Theories
A thorough and rigorous analysis of electromagnetic fields in cavities This book offers a comprehensive analysis of electromagnetic fields in cavities of general shapes and properties. Part One covers classical deterministic methods to conclude resonant frequencies, modal fields, and cavity losses; quality factor; mode bandwidth; and the excitation of cavity fields from arbitrary current distributions for metal-wall cavities of simple shape. Part Two covers modern statistical methods to analyze electrically large cavities of complex shapes and properties. Electromagnetic Fields in Cavities combines rigorous solutions to Maxwell's equations with conservation of energy to solve for the statistics of many quantities of interest: penetration into cavities (and shielding effectiveness), field strengths far from and close to cavity walls, and power received by antennas within cavities. It includes all modes and shows you how to utilize fairly simple statistical formulae to apply to your particular problem, whether it's interference calculations, electromagnetic compatibility testing in reverberation chambers, measurement of shielding materials using multiple cavities, or efficiency of test antennas. Electromagnetic Fields in Cavities is a valuable resource for researchers, engineers, professors, and graduate students in electrical engineering.

This flexible resource contains lesson plans and worksheets to inspire pupils of poetry and literature. It is a choice alternative to past exam paper practice. This book contains everything an English teacher could need to engage and captivate their pupils in contemporary poetry and prose. The step-by-step lesson plans are easy to adapt to suit individual teachers' needs, and include suggestions for utilising ICT and homework ideas. The reflective style of the photocopiable worksheets encourages pupils to draw on their own experiences when analysing the issues raised. The contents are themed to reflect the current curriculum, and to be entertaining for the teacher and students alike. Extracts include "In Mrs Tilscher's Class" by Poet Laureate, Carol Ann Duffy and "To Sir, With Love" by E.R.Braithwaite. English teachers and pupils aged 14-16 will relish this set of inclusive and accessible lesson plans and worksheets, although advanced younger pupils or adult learners, especially those on EFL courses, will also find them absorbing. All materials are also available for download from the Continuum website. It's hard enough for teachers to fit all their marking, extra-curricular duties and training into their lives, let alone finding time to think up exciting new ways of delivering their subject to a mixed-ability class. This new series offers complete, curriculum-friendly lesson plans for busy secondary school teachers of various disciplines. Each title includes an assortment of approximately 70 lesson plans designed to motivate and inspire students. Each plan consists of a teacher's sheet, providing: the aims and objectives of the lesson; the materials required; a lesson starter, main lesson plan and plenary, each with suggested timeframes to help teachers keep inside the parameters of the lesson; homework ideas, and guidance on how to adapt the activities to make them harder or easier for gifted and talented, or less able pupils. Each plan also includes a photocopiable, or downloadable student worksheet which corresponds to the teacher's lesson plan.
