Popis:	We investigate theoretically the magnetic vector barrier transmission of Dirac-like particles in a lattice, which can be described by a Dirac-like Hamiltonian associated with a pseudospin one. We consider the transmission of Dirac-like particles through a single magnetic vector barrier and double ones. It has been found that the motion of the particles through a single barrier and that through two parallel barriers give both asymmetric transmission and symmetric transmission for antiparallel double barriers.
