Efficient, robust and accurate algorithms are proposed for solving the multiple
scattering problem by M circular obstacles for the whole spectrum of frequency.
The representation of the solution is based on an integral equation formulation
next solved by using Fourier basis. Numerical examples are provided to show
that the approaches are efficient.
