Terahertz(THz) imaging provided a good contrast between skin cancer (basal cell carcinoma BCC) and healthy tissue in vitro and ex vivo owing to the high water content and strong absorption of cancer tissue at THz frequencies .Modeling the propagation of a THz pulse through BCC would contribute to revealing the diagnostic and potential therapeutic application value of THz radiation. In this letter, the healthy skin and BCC were modeled as Double Debye dispersive media and the model was incorporated into the FDTD method to simulate the propagation of a THz pulse. Furthermore, absorption properties were revealed by calculating average SAR value of the horizontal distribution and vertical distribution, which would help investigate the response below the skin surface.
