Abstract

In this chapter, we discuss the boundary value problems of Helmholtz equation, which is from the time-harmonic acoustic scattering (Colton & Kress, 2013). Consider the acoustic wave propagation in a homogeneous isotropic medium with density $$\rho _0$$ ρ 0 , speed of sound $$c_0$$ c 0 and damping coefficient $$\gamma _0$$ γ 0 in $$ \mathbb R^n$$ R n ( $$n=2, \, 3$$ n = 2 , 3 ), where the constant $$\rho _0>0, c_0>0$$ ρ 0 > 0 , c 0 > 0 and $$\gamma _0\geqslant 0$$ γ 0 ⩾ 0 .
