A technique to measure the complex permittivity and permeability using two different types of calibration is presented in this article. The technique is based on a classical transmission-line analysis, implemented on a strip-line structure. A new calibration technique, namely object-reflect-line (ORL), is proposed to meet the challenge of an extremely low reflection line for accurate measurement. In the proposed calibration, the thru standard of conventional thru-reflect-line (TRL) is replaced by a standard with a known object. Since the ORL calibration uses only a single device, it reduces the fabrication cost, the measurement complexity, and the potential error in the thru measurement needed in the TRL method, which uses an additional device. The analysis is extended with consideration of the impact on material loss in measurement accuracy. The simulated and measured results with a variety of nonmagnetic and magnetic materials demonstrate the effectiveness of the proposed method over broadband microwave frequencies.

复介电常数和磁导率的校准宽带测量技术

本文介绍了一种使用两种不同类型的校准来测量复介电常数和磁导率的技术。该技术基于经典的传输线分析，在带状线结构上实施。提出了一种新的校准技术，即物体反射线（ORL），以应对极低反射线的精确测量挑战。在建议的校准中，传统直通反射线 (TRL) 的直通标准被具有已知物体的标准所取代。由于 ORL 校准仅使用单个设备，因此它降低了制造成本、测量复杂性以及使用附加设备的 TRL 方法所需的直通测量中的潜在误差。考虑到材料损失对测量精度的影响，对分析进行了扩展。
