| Outline of Final Research Achievements |
This study aims to realize the dielectric material evaluation technology for the 100 GHz band, which is a fundamental element technology for the development of advanced electronic devices in the 75-110 GHz band, considered for next-generation communication technologies.
Using the newly developed 100 GHz band TM0m0 mode cavity resonator, the complex permittivity of thermoplastic resin rods was evaluated, revealing their dielectric properties. By comparing these results with the continuously expanded complex permittivity database, the effectiveness of this evaluation technology was verified. The measurement accuracy has approximately ±3% for the relative permittivity and ±5% for the loss tangent, respectivly.
This technology will be expected to accelerate the development of various dielectric materials applicable to next-generation communication technologies.
