Radiowave Propagation Over Ground Software


Book Description

The purpose of the package is to answer the question 'What is the radio field strength at a certain point?' when power is radiated from a transmit ting source. Because of the complexity of the question in general, it can only be answered at present in certain idealized situations. Nevertheless it is valuable to have quantitative data available for these situations. The package is divided into two parts. In the first of these, propagation in free space and over a flat earth are dealt with. In the second, propagation over a spherical earth is considered. In the free-space situation the power density of the signal in a given direction will fall as the inverse square of the distance from the source. For propagation from a transmitting source at an arbitrary height above a perfecdy conducting flat earth, the field strength at large distances can be 3 dB higher than in free space. With a finite conduc tivity earth, the field strength will be lower than this because of the power dissipation in the earth.




Radiowave Propagation Over Ground


Book Description

This is the first book devoted to radiowave propagation over land and sea. Researchers and engineers involved in propagation studies and applications in communications, broadcasting, radar and remote sensing will find this volume invaluable.




Propagation of Radiowaves


Book Description

This book has been fully updated to reflect the latest developments in the field of radio communications. This book introduces the basic concepts and mechanisms of radiowave propagation engineering in both the troposphere and ionosphere, and includes greater emphasis on the needs of digital technologies and new kinds of radio systems.




Satellite-to-Ground Radiowave Propagation


Book Description

This book is a follow-up to the award-winning first edition and is written as a comprehensive guide for those who need to obtain a working knowledge of radiowave propagation on satellite-to-ground links at frequencies above 1 GHz and as a reference book for experts in the field. To accomplish this, expanded sections of explanatory text, copiously illustrated, enable an undergraduate or non-specialist to grasp the fundamentals involved. An extensive reference list permits the expert to go to the source material should the level of enquiry go beyond the level of this book.




Electromagnetic Waves


Book Description

This book provides a comprehensive treatment of electromagnetic waves. The author's approach is thoroughly modern, and unlike many others, this text offers a unified view of electromagnetic waves and their applications in telecommunications, radar, and photonics. The extensive coverage of Electromagnetic Waves begins with Maxwell's equations and takes students on the journey from the wave and Helmholtz equations through polarization, plane waves, and wave beams and packets, to antennas, transmission lines, and waveguides. Completing the treatment are chapters devoted to diffraction and an introduction to the theory of coherence. The author strikes an effective balance of the teach-through-concepts and teach-by-example approaches. The book is filled with exercises, current applications, and exercises that solidify students' understanding and bring relevance to the material. It forms an outstanding text for senior undergraduates and graduate-level students in electrical engineering and physics.
















RF and Microwave Engineering


Book Description

This book provides a fundamental and practical introduction to radio frequency and microwave engineering and physical aspects of wireless communication In this book, the author addresses a wide range of radio-frequency and microwave topics with emphasis on physical aspects including EM and voltage waves, transmission lines, passive circuits, antennas, radio wave propagation. Up-to-date RF design tools like RF circuit simulation, EM simulation and computerized smith charts, are used in various examples to demonstrate how these methods can be applied effectively in RF engineering practice. Design rules and working examples illustrate the theoretical parts. The examples are close to real world problems, so the reader can directly transfer the methods within the context of their own work. At the end of each chapter a list of problems is given in order to deepen the reader’s understanding of the chapter material and practice the new competences. Solutions are available on the author’s website. Key Features: Presents a wide range of RF topics with emphasis on physical aspects e.g. EM and voltage waves, transmission lines, passive circuits, antennas Uses various examples of modern RF tools that show how the methods can be applied productively in RF engineering practice Incorporates various design examples using circuit and electromagnetic (EM) simulation software Discusses the propagation of waves: their representation, their effects, and their utilization in passive circuits and antenna structures Provides a list of problems at the end of each chapter Includes an accompanying website containing solutions to the problems (http:\\www.fh-dortmund.de\gustrau_rf_textbook) This will be an invaluable textbook for bachelor and masters students on electrical engineering courses (microwave engineering, basic circuit theory and electromagnetic fields, wireless communications). Early-stage RF practitioners, engineers (e.g. application engineer) working in this area will also find this book of interest.
