Webwhere electromagnetic waves penetrate only minimally into a good conductor. In addition, thermal waves are strongly dispersive. Their phase velocity is directly dependent on the modulation frequency of the heat source. Therefore, it is not possible to produce propagating wave packets, since each partial wave propagates at its own phase velocity. 2. WebOn the wave theory of heat conduction. J.
