Abstract

Analytical expressions are derived for the size and width of the frequency crossing signals that are observed in the thermal conductivity of a dielectric when the frequencies of two resonant scattering processes are made equal. The expressions apply in the low concentration limit and are extended to higher concentrations by computer analysis.
