| Abstract: | Based on the hyperbolic equation of heat conduction,using the expansion method of complex functions,multiple scattering of thermal waves from subsurface cylinders in the semi-infinite slab was investigated.A general solution of the thermal wave scattering was given.The thermal waves were excited at surfaces of opaque materials by modulated optical beams.The effects of geometrical and physical parameters on the temperature distribution were analyzed.The circular cylinder was taken as a cavity with thermal insulation conditions.The theory and numerical results of this paper can be used for infrared thermal wave imaging,physical inverse problem and evaluation of internal defects in materials. |
