We use the Wick-rotated time-dependent supersymmetry to construct models of two-dimensional Dirac fermions in presence of an electrostatic grating. We show that there appears omnidirectional perfect transmission through the grating at specific energy. Additionally to being transparent for incoming fermions, the grating hosts strongly localized states.

    DS II breather profiles become the potentials and mass terms of planar Dirac Hamiltonians with omnidirectional perfect transmission, yielding a three-parameter SKT family with embedded bound states.
