摘要：

In this study, we present a complex domain sampling for determining the coefficients of the rational function model (RFM) based on biological tissue properties. The RFM converts the reflection coefficient (measured using the open-ended coaxial probe) to complex permittivity. The complex domain sampling reduces the number of different permittivity samples needed to calculate the RFM coefficients, hence improving the efficiency of the model. It also could allow the RFM coefficients to be determined from experimental measurements.
