It is demonstrated that low energy pair collisions of bosonic atoms with isotropic interatomic interaction in harmonic waveguides can lead to coupled s- and d-wave confinement-induced resonances (CIRs). In analogy to the extensively studied s-wave case, we show that the d-wave CIR effect emerges in the quasi-1D regime of the confining trap as an imprint of the 3D d-wave resonant scattering properties. The presence of the centrifugal barrier for higher partial waves modifies the confinement strength dependence of the resonant condition, which is determined for the parameters of the applied model. The effect can be utilized for the realization of confined atomic gases interacting via higher partial waves and opens a novel possibility for studying such correlated atomic systems.
