| Summary: | —This paper presents the application of unconditionally stable fundamental finite-difference time-domain (FADI-FDTD) method
in modeling the interaction of terahertz pulse with healthy skin and
basal cell carcinoma (BCC). The healthy skin and BCC are modeled as
Debye dispersive media and the model is incorporated into the FADIFDTD method. Numerical experiments on delineating the BCC margin from healthy skin are demonstrated using the FADI-FDTD method
based on reflected terahertz pulse. Hence, the FADI-FDTD method
provides further insight on the different response shown by healthy
skin and BCC under terahertz pulse radiation. Such understanding of
the interaction of terahert pulse radiation with biological tissue such
as human skin is an important step towards the advancement of future
terahertz technology on biomedical applications. |
