【Abstract】 In this paper, based on non-Fourier’s law of heat conductivity, using the expansion method of wave functions the thermal wave scattering of two subsurface cylinders in semi-finite solids is investigated. A general solution of scattered wave based on wave equations of heat conduction is given. The effect of physical parameters on the temperature distribution is analyzed. The thermal waves are excited at surfaces of opaque materials by modulated optical beams. The circular cylinder is taken as a cavity with thermal insulation conditions. At last, numerical results are presented graphically.更多还原
