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.","authors_text":"A. A. Andrianov, S. S.
