Abstract

Abstract: Based on finite element and artificial transmitting boundary method, the cylindrical wave scattering by infinite circular cylinder is computed and compared with analytical solution. Then other problems on scattering induced by irregular objects are also solved on use of the same method, whose superiority and efficiency have been indicated by numerical examples.

Key words: finite element, artificial transmitting boundary, irregular objects, cylindrical wave scattering
