摘要

本文提出了一种在印刷电路板上实现的廉价传感器，用于液体和固体的宽带介电特性。它基于CPW-CPW转换和统计校准。该方法的特点是，由于电介电常数是通过单层校准获得的，因此无需对具有不同性质的级联传输线进行假设。该传感器通过甲醇和PDMS的测量进行了验证。

An inexpensive backside-sensing coplanar waveguide sensor for characterization of liquids and solids up to 40 GHz

We present in this paper an inexpensive sensor realized on printed circuit board for broadband dielectric characterization of both liquids and solids. It is based on a CPW-CPW transition and statistical calibration. The specific property of the approach is that no assumption regarding cascading transmission lines with different properties has to be made as permittivity is obtained by a single-tier calibration. The sensor is validated by measurements of methanol and PDMS.
