Abstract
The microwave conductivity and the surface resistance are calculated f or systems with a strong electron-phonon interaction. It is shown that the real part of the conductivity has a maximum at intermediate tempe ratures in the clean limit in accordance with the experimental observa tion in high-T(c) superconductors. This maximum connects with the temp erature dependence of the electron relaxation rate and is not the cohe rence peak. But this phenomenon can not be described properly in terms of a simple two-fluid model.
