  The electrodynamics supplemented with a Chern-Simons (CS) action
(Carrol-Field-Jackiw electrodynamics) in a half space is studied. The passage
of photons and/or massive vector mesons through a boundary between the CS
medium and the vacuum of conventional Maxwell electrodynamics is investigated.
Effects of reflection from a boundary (up to the total one) are revealed when
vector particles escape to vacuum and income from vacuum passing the boundary.
Both the space-like and time-like CS vectors are considered.
