Klappentext The first book on DPSM-a patented new technology that is superior for solving/modeling engineering problemsIn the last few decades, numerical methods like Finite Element Method (FEM) and Boundary Element Method (BEM) have been used for solving a variety of engineering problems in bounded and unbounded geometries, but they are not interchangeable across homogeneous and inhomogeneous media and encounter difficulties at high frequencies. Now, Distributed Point Source Method (DPSM) has been developed for solving ultrasonic, magnetic, electrostatic, and electromagnetic engineering problems with a single, unified technique.In DPSM-unlike FEM and BEM-it is not necessary to discretize or mesh the problem geometry or its boundary. Instead, point sources are placed near the boundaries and interfaces to build a model that can correctly take into account the radiation and continuity conditions at these interfaces, making it a faster and more versatile method than the conventional numerical techniques.Valuable for graduate students and engineers in research and development, this book covers basic and advanced theories and applications of DPSM and includes a User's Manual for the DPSM-based computer program.
