Explore how sound pulses diffract around a circular cylinder and how the math predicts the resulting pressure fields.
This book develops the theory of diffracted pulses behind a circular cylinder in two dimensions, using Green’s functions and a careful treatment of boundary conditions. It shows how the incident pulse and its diffracted counterparts are related through a Laplace-Fourier framework, and it connects acoustics to analogous electromagnetic problems.
- Learn how the Green’s function is formulated for a cylinder and how it leads to the diffracted pressure field.
- See how the problem is analyzed with transforms and special functions, including how fronts propagate and how caustics arise.
- Understand the connections between acoustic and electromagnetic boundary conditions and how the same method applies to both.
- Get insights into numerical results and asymptotic behavior for specific geometries and pulse shapes.
Ideal for readers of advanced acoustics, wave theory, and applied physics who want a rigorous, workmanlike treatment of diffraction by curved surfaces.
