This paper theoretically explores the non-Fourier heat conduction process initiated by a rectangular pulsed heat source in a finite slab with insulated boundaries. Green's function and finite integral transform technique are used to obtain analytical solutions for tempera ture fields in the slab. The propagation and reflection of thermal wave, the effects of heat source and slab's geometric parameter on temperature fields are discussed. It is found that temperature wave frequency at a given location in the s lab is relevant to slab's thickness and its thermal relaxation time while the amplitude of temperature wave bears a relation with heat source's distribution are a and pulse duration.
