Abstract: In the system of planar exchange-coupled antiferromagnetic layers with and without an inversion center, the hybridization of waveguide and antiwaveguide spin wave propagation modes induces an interference mechanism of resonant enhancement of both the amplitudes of evanescent magnons and the accompanying first order effects of nonspecular spin-wave refraction in the course of transmission and (or) reflection processes (including those corresponding to the magnon analog of Fano resonance).
