Abstract

The Four-Zero dispersive media model is derived for human breast tissue. This model is ideally suited for the finite-difference time-domain (FDTD), while accurately matching recently published measured values over the 500 MHz-20 GHz microwave frequency band. The Four-Zero model requires just two additional electric field and one additional magnetic field stores, yet agrees with measured data to within 4% across almost two decades of frequency, comparable to measurement uncertainty
