Abstract

The open-ended coaxial sensor is modeled by a non-uniform FDTD method. Such sensors are used for complex permittivity measurements in the MHz-GHz frequency range. The accuracy of the measurements depend greatly on the accuracy of the reflection coefficient computation. The non-uniform grid makes it possible to use very fine discretization in the critical area where the open-end of the coax is attached to the sample. The method can be used to calculate the reflection coefficient for very thin samples.

开放式同轴传感器的非均匀时域有限差分法精确建模

采用非均匀时域有限差分法对开放式同轴传感器进行了建模。这种传感器用于在MHz-GHz频率范围内的复杂介电常数测量。测量结果的准确性在很大程度上取决于反射系数计算的准确性。非均匀网格使得在同轴电缆的开放端附着在样品上的关键区域使用非常精细的离散化成为可能。该方法可用于计算极薄样品的反射系数。
