This letter proposes a microwave planar sensor for the characterization of magnetodielectric materials. The sensor is designed by loading microstrip lines with complementary split-ring resonators (CSRRs). Two patches are connected to the microstrip lines to couple with the CSRRs, and a pair of 50- $\Omega $ resistors are in series with the lines to provide a notch. The designed sensor can extract the permittivity and permeability of the magnetodielectric materials simultaneously. A prototype of the designed sensor is fabricated and measured for validation of characterizing the magnetodielectric materials.

用于同时测量介电常数和磁导率的加载 CSRR 的平面传感器

这封信提出了一种用于表征磁介电材料的微波平面传感器。该传感器是通过加载带有互补裂环谐振器 (CSRR) 的微带线来设计的。两个贴片连接到微带线以与 CSRR 耦合，以及一对 50- $\欧米茄 $ 电阻器与线路串联以提供一个缺口。设计的传感器可以同时提取磁介电材料的介电常数和磁导率。制造和测量设计传感器的原型，以验证表征磁介电材料。
