The quasiparticle interference (QPI) patterns in ${\mathrm{BiS}}_{2}$-based superconductors are theoretically investigated by taking into account the spin-orbital coupling and assuming the recently proposed ${d}_{{x}^{2}\ensuremath{-}{y}^{2}}^{*}$-wave pairing symmetry. We found two distinct scattering wave vectors whose evolution can be explained based on the evolution of the constant-energy contours. In addition, we also …
