AB  - The ability to tune interparticle interactions is one of the main advantages of using ultracold quantum gases forquantum simulation of many-body physics. Current experiments with ultracold polar molecules employ shielding with microwave or static electric fields to prevent destructive collisional losses. The interaction potential ofmicrowave-shielded molecules can be tuned by using microwaves of two different polarizations, while for static-field-shielded molecules the tunability of interactions is more limited and depends on the particular species.In this work, we propose a general method to tune the interactions between static-field-shielded molecules byapplying a microwave field. We carry out coupled-channel scattering calculations in a field-dressed basis set todetermine loss rate coefficients and scattering lengths. We find that both the s-wave scattering length and thedipole length can be widely tuned by changing the parameters of the microwave field, while maintaining strong suppression of lossy collisions.
