Electromagnetic Testing System for Measurement of Low Conductivity Objects

Abstract

Abstract Electromagnetic testing technology has been widely adopted in industrial process parameter detection, biomedical engineering and other fields due to its fast response, non-contact, non radiation and low cost features. However, measurement of low conductivity objects has always been considered a challenge in the field of electromagnetic testing, due to factors such as low signal sensitivity and data processing complexity, etc. An electromagnetic testing system is presented in this paper, which achieves the detection and extraction of electrical characteristic parameters of low conductivity objects by optimizing sensors, increasing operating frequency, improving effective data transmission and processing etc. Its performance is verified through imaging experiments.
