A theory of dissipative nonlinear conductivity, $\sigma_1(\omega,H)$, ofs-wave superconductors under strong electromagnetic fields at low temperaturesis proposed. Closed-form expressions for $\sigma_1(H)$ and the surfaceresistance $R_s(\omega,H)$ are obtained in the nonequilibrium dirty limit forwhich $\sigma_1(H)$ has a significant minimum as a function of a low-frequency$(\hbar\omega\ll k_BT)$ magnetic field $H$. The calculated microwavesuppression of $R_s(H)$ is in good agreement with recent experiments on alloyedNb resonator cavities. It is shown that superimposed dc and ac fields,$H=H_0+H_a\cos\omega t$, can be used to reduce ac dissipation in thin filmnanostructures by tuning $\sigma_1(H_0)$ with the dc field.
