Abstract
A theoretical treatment is given of the dispersion relation for the propagation of high-frequency thermal waves in nonconducting crystals. The wavenumber dependence of the thermal phonon relaxation times is taken into account, and complementary analytical and numerical methods are developed to obtain the dispersion relation.Keywords
