Abstract

This work presents an improved noncontact electromagnetic probe for near-field diagnosis and characterization, driven by a network vector analyzer (VNA) operating in the frequency range of 1 kHz to 1 GHz. Two configurations of a modified near-field microstrip probe (NFMP) are designed and studied, featuring a tip and a dipole termination. Simulations and experimental tests are conducted to assess the probe performances in detecting microcracks. Notably, the detection of cracks of 10 × 20 × 30 μm is achieved by leveraging the shift in resonance frequency. However, the impedance mismatch between the VNA and the probe presents a challenge to the system sensitivity. To address this limitation, a modification is proposed, introducing a surface-adjustable capacitance to the microstrip. This enhancement improves the probe sensitivity and enables full adjustability during measurements. An improvement of 27.13 dB in the reflection parameter is obtained. The developed probes provide nondestructive testing capabilities across a wide frequency range, from 1 kHz to 1 GHz, making them well-suited for integration with VNA systems and facilitating rapid and reliable external measurements.

用于诊断和材料表征的增强型电磁近场探针
这项研究提出了一种用于近场诊断和鉴定的改进型非接触式电磁探头,由工作频率范围为 1 kHz 至 1 GHz 的网络矢量分析仪 (VNA) 驱动。我们设计并研究了改进型近场微带探头(NFMP)的两种配置,即尖端和偶极终端。通过模拟和实验测试,评估了探头在探测微裂纹方面的性能。值得注意的是,通过利用共振频率的偏移,实现了对 10 × 20 × 30 μm 裂纹的检测。然而,VNA 和探头之间的阻抗失配给系统灵敏度带来了挑战。为了解决这一限制,我们提出了一种改进方法,在微带上引入表面可调电容。这一改进提高了探头灵敏度,并在测量过程中实现了完全可调。反射参数提高了 27.13 dB。所开发的探头可在 1 kHz 至 1 GHz 的宽频率范围内进行无损测试,因此非常适合与 VNA 系统集成,便于进行快速可靠的外部测量。

期刊介绍: Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
