The Diffraction of Oblique Surface Waves by a Right-Angle Bend (Classic Reprint)


Book Description

Excerpt from The Diffraction of Oblique Surface Waves by a Right-Angle Bend In this paper we discuss the diffracted field that arises when an incident electromagnetic surface wave strikes the edge of a right - angle bend at an oblique angle. One face of the bend which supports the surface wave is an impedance plane and the other face is a perfector conductor. The edge of the bend may be either parallel or perpendicular to the perfectly conducting direction of the impedance plane. The diffraction of normally incident surface waves by a right - angle bend and its implication for surface.

Acoustic Absorbers and Diffusers


Book Description

Absorbers and diffusers are two of the main design tools for altering the acoustic conditions of rooms, semi-enclosed spaces and the outdoor environment. Their correct use is important for delivering high quality acoustics. Unique and authoritative, this book decribes how to effectively measure, model, design and apply diffusers and absorbers. It is a resource for new and experienced acousticians, seeking an understanding of the evolution, characteristics and application of modern diffusers. Absorption is a more established technology and so the book blends traditional designs with modern developments. The book covers practical and theoretical aspects of absorbers and diffusers and is well illustrated with examples of installations and case studies. This new edition brings Acoustic Absorbers and Diffusers up-to-date with current research, practice and standards. New developments in measurement, materials, theory and practice since the first edition (published in 2004) are included. The sections on absorbers are extended to include more about noise control.




The Diffraction of Oblique Surface Waves by a Right-angle Bend


Book Description

The diffracted field that arises when an incident electromagnetic surface wave strikes the edge of a right-angle bend at an oblique angle is investigated. One face of the bend supports the surface wave and the other face is a perfect conductor. This diffraction problem is related to the scanning surface wave antennas. An analysis of oblique surface waves on an infinite impedance plane is first presented graphically. We treat two cases. In one case the edge of the bend is parallel, and, in the other case, perpendicular, to the perfectly conducting direction of the impedance plane. When the surface wave is incident normally, these special cases reduce to the normal TM and TE surface waves respectively. The mathematical formalism of the first case may bb y be reduced to that of a two dimensional TM problem which has been solved previously. The second case involves two coupled mixed boundary conditions and is exactly analyzed in detail. The effect of the obliquity on the reflection coefficient and the radiation pattern under various conditions is discussed. (Author).




Fundamentals of Semiconductors


Book Description

Excellent bridge between general solid-state physics textbook and research articles packed with providing detailed explanations of the electronic, vibrational, transport, and optical properties of semiconductors "The most striking feature of the book is its modern outlook ... provides a wonderful foundation. The most wonderful feature is its efficient style of exposition ... an excellent book." Physics Today "Presents the theoretical derivations carefully and in detail and gives thorough discussions of the experimental results it presents. This makes it an excellent textbook both for learners and for more experienced researchers wishing to check facts. I have enjoyed reading it and strongly recommend it as a text for anyone working with semiconductors ... I know of no better text ... I am sure most semiconductor physicists will find this book useful and I recommend it to them." Contemporary Physics Offers much new material: an extensive appendix about the important and by now well-established, deep center known as the DX center, additional problems and the solutions to over fifty of the problems at the end of the various chapters.




The Physics of Radiation Therapy


Book Description

Dr. Khan's classic textbook on radiation oncology physics is now in its thoroughly revised and updated Fourth Edition. It provides the entire radiation therapy team—radiation oncologists, medical physicists, dosimetrists, and radiation therapists—with a thorough understanding of the physics and practical clinical applications of advanced radiation therapy technologies, including 3D-CRT, stereotactic radiotherapy, HDR, IMRT, IGRT, and proton beam therapy. These technologies are discussed along with the physical concepts underlying treatment planning, treatment delivery, and dosimetry. This Fourth Edition includes brand-new chapters on image-guided radiation therapy (IGRT) and proton beam therapy. Other chapters have been revised to incorporate the most recent developments in the field. This edition also features more than 100 full-color illustrations throughout. A companion Website will offer the fully searchable text and an image bank.
