Kinetic properties of corrugated and thread-like intermediate state structures

The heat conductivity and acoustic absorption in corrugated and thread-like structures of the intermediate state of a superconductor with a free mean path exceeding the thickness of the normal phase interlayer are calculated by the kinetic equation method. The shape of the phase interface and the conduction electron dispersion law are assumed arbitrary. It is established that the kinetic properties of the structures being studied are formed by electron excitations in the neighborhood of Fermi-surface reference points and contain information about the local electron spectrum parameters.
