  The electron-hole conversion at the normal-metal superconductor interface in
inversion-symmetric Weyl semimetals is investigated with an effective two-band
model. We find that the specular Andreev reflection of Weyl fermions has two
unusual features. The Andreev conductance for s-wave BCS pairing states is
anisotropic, depending on the angle between the line connecting a pair of Weyl
points and the normal of the junction, due to opposite chirality carried by the
paired electrons. For the Fulde-Ferrell-Larkin-Ovchinnikov pairing states, the
Andreev reflection spectrum is isotropic and is independent of the finite
momentum of the Cooper pairs.
