A1 Sirenko, Yuriy T1 PHASE AND GROUP VELOCITIES OF ELECTROMAGNETIC WAVES IN A MONOCLINIC CRYSTAL JF Telecommunications and Radio Engineering JO TRE YR 2019 FD 2019-02-01 VO 78 IS 1 SP 1 OP 10 K1 anisotropy K1 rhombic symmetry K1 monoclinic crystal K1 ?? and ?? electromagnetic waves K1 phase and group velocities K1 electromagnetic energy flux AB Based on the matrizer technique, indicatrices of the phase vector and phase and group velocities have been firstly constructed in analytical form for TE and TM electromagnetic waves in a monoclinic crystal. A representation has been derived for the energy flux in such an anisotropic medium, and coincidence of the direction of the respective vector with the group velocity direction of the electromagnetic wave is demonstrated.
