Paperback. Condición: New. Print on Demand. This book investigates diffraction at high frequencies, delving into a singular integral equation to solve problems unsolvable through lower frequency methods. The author provides a new integral equation suitable for high frequencies and develops a procedure for obtaining an asymptotic expansion, especially useful for these frequencies. Though a direct iteration on this equation fails, an indirect method proves more successful. Each iterate of this method is of lower order than the preceding and the general term is given, allowing for error estimation. The book places a particular focus on circular discs and provides detailed calculations for a plane wave striking the disc normally. The corresponding integral equations for sound-hard discs are also derived and their iterative procedures described. The distribution on the disc and scattering coefficient are determined, with the latter being presented in asymptotic form. Ultimately, this book makes a significant contribution to the study of high frequency diffraction and deepens our understanding of this phenomenon.
