Debye Coefficients for Biological Tissues From 100 MHz to 100 GHz
Keywords:
Debye, dispersive media, FDTD method, frequency domainAbstract
Debye modeling of dispersive, biological tissues allows for the numerical analysis of electromagnetic waves in the vicinity of a human body using the FDTD method. Three-term Debye expansion coefficients for 55 human biological tissues are determined via a two-step numerical solver. The Debye coefficients obtained predict precisely the complex permittivity of the experimentally available tissue data.
