Synopsis

This book marks a groundbreaking moment in the history of physics as the author introduces a new theory of wave propagation - the geometrical theory of diffraction or GTD. GTD's origins lie in geometrical optics, yet it extends far beyond it, explaining phenomena like diffraction, which account for the bending of light around corners and the formation of shadows. By combining optical principles such as phase variation and energy conservation, the author develops a formula which determines the total field diffracted by any aperture, as well as the field in the aperture itself or the far field diffraction pattern. The book also considers the transmission cross-section of the aperture and provides explicit formulas and numerical results for various shapes, demonstrating the theory's accuracy even at larger wavelengths. The author's novel approach has paved the way for new discoveries in diffraction theory and its applications, proving particularly useful in examining diffraction by objects of any shape, both smooth and with sharp edges.
