Excerpt from Diffraction by a Circular Aperture at High Frequencies
The mathematical analysis of diffraction phenomena has been significantly extended in recent years. A variety of methods, new and old, have proved their worth in enlarging the roster of problems amenable to calculation, particularly as regards configurations of geometrical complexity. It should be remarked, however, that the form of solutions thus Obtained may not always be well suited for describing certain features of the scattering problem, such as the high frequency or shortawavelength characteristics. The latter can be recognized in the zero-wavelength (or geometrical optics) limit, although without the inter esting distinction that is manifest at long wavelengths, say, between like scatterers of different composition. To exhibit a corresponding difference in the scattering at high frequencies one must refine the geometrical optics approxi mation.

Paperback. Condizione: New. Print on Demand. This book delves into the field of diffraction, a fascinating phenomenon that occurs when a wave encounters an obstacle and explores its properties in the context of circular apertures and screens. The author provides a comprehensive analysis of the intricate relationship between the wave's characteristics and its interaction with these geometric shapes, delving into the complexities of transmission and scattering. The book's detailed explanations and use of integral equations and variational principles offer a thorough understanding of the subject's theoretical foundations. It not only explains established concepts but also presents original research, significantly expanding our knowledge of wave behavior in the presence of apertures and screens. The insights gained from this book contribute to the broader field of wave propagation and have important implications for applications in diverse areas such as optics, acoustics, and electromagnetism, making it an invaluable resource for researchers and students alike.
