Abstract

Measurement of the dielectric properties of ocular tissues up to 110 GHz was performed by the coaxial probe method. A coaxial sensor was fabricated to allow the measurement of small amounts of biological tissues. Four-standard calibration was applied in the dielectric property measurement to obtain more accurate data than that obtained with conventional three-standard calibration, especially at high frequencies. Novel data of the dielectric properties of several ocular tissues are presented and compared with data from the de facto database.

摘要

采用同轴探头法对高达110 GHz的眼组织介电特性进行了测量。制作了一种同轴传感器，用于测量少量生物组织。在介电特性测量中采用四标准校准，以获得比传统三标准校准更准确的数据，尤其是在高频时。给出了几种眼组织介电特性的新数据，并与实际数据库中的数据进行了比较。
