The paper deals with a class of shape/topology optimization
problems governed by the Helmholtz equation in 2D. To guarantee the
existence of minimizers, the relaxation is necessary. Two numerical methods
for solving such problems are proposed and theoretically justified: a direct
discretization of the relaxed formulation and a level set parametrization of
shapes by means of radial basis functions. Numerical experiments are
given.
