[China Instrument Network Instrument R&D] On January 31, 2018, Shanghai Institute of Metrology, Institute of Electronic and Electrical Research, Quality Inspection Bureau, “Research on Low Dielectric Constant Measurement Device Based on FSS Resonance Method” (Project Number: 2016-07) Successfully passed expert acceptance.

In this project, with the continuous expansion of the application range of dielectric materials, the low dielectric constant measurement of dielectric materials has become a research hotspot. A set of multi-resonant test points and wide-band pass test systems have been developed to realize the introduction of multiple frequency points in the X-band. The electrical constant test solves the problem that the existing resonance method technology can only test a single frequency point.
The project applied for 1 invention patent, published 2 international conference papers, completed various assessment tasks, and reached the domestic leading level.
The development of this project has positively responded to the inclusion of the “Measurement Criteria for the Improvement of Materials Testing Technology” and “Applicability of Materials Testing Technology Standards” in the “New Materials Industry Development Guideline” and “The 13th Five-Year Plan for Materials Specialization in Scientific and Technological Innovation”. "Development priorities" promote the application of dielectric materials with low dielectric constants in microwave communications, radar navigation, satellite communications, remote sensing telemetry, and biomedical applications, and provide technical support for dielectric constant measurement of new low-loss dielectric materials. .
