摘要

估计生物组织在微波频率下的介电特性对许多应用都很有意义。传统的同轴探针方法进行局部测量，对生物组织中常见的非均质或层状材料的使用有限。为了克服这一问题，开发了一种能够估计生物组织体介电特性的专用天线系统和校准技术。利用天线系统对异质离体生物组织的介电特性进行了估计。

Estimating bulk dielectric properties of biological tissues at microwave frequencies

Estimating the dielectric properties of biological tissues at microwave frequencies is of interest for numerous applications. Conventional coaxial probe methods perform local measurements which are of limited use for heterogeneous or layered materials common in biological tissues. To overcome this, a dedicated antenna system and calibration technique capable of estimating bulk dielectric properties of biological tissues has been developed. Dielectric properties of heterogeneous ex vivo biological tissues were estimated using the antenna system.
