  We first investigate spectral properties of the Neumann-Poincar\'e (NP)
operator for the Lam\'e system of elasto-statics. We show that the
elasto-static NP operator can be symmetrized in the same way as that for
Laplace operator. We then show that even if elasto-static NP operator is not
compact even on smooth domains, its spectrum consists of eigenvalues which
accumulates to two numbers determined by Lam\'e constants. We then derive
explicitly eigenvalues and eigenfunctions on disks and ellipses. We then
investigate resonance occurring at eigenvalues and anomalous localized
resonance at accumulation points of eigenvalues. We show on ellipses that
cloaking by anomalous localized resonance takes place at accumulation points of
eigenvalues.
