Outline of Final Research Achievements

For the purpose of measuring permittivity and permeability (material constants) of non-solid materials, a new method using plastic cases which can contain the material was examined. The case was manufactured using a 3-D printer. Material constants were estimated from measured S parameters using high-frequency circuit theorem. It was experimentally found that the proposed method enables to measure powder and oriented magnetic material. Moreover, it is expected that measurement error will be reduced by taking account of higher mode derived from a complex structure of the case.

Academic Significance and Societal Importance of the Research Achievements

本提案手法により,農林水産物由来の物質や生体物質,電磁波エネルギー損失材料といった非固体ならびに配向付与材料の測定がより簡便になることが学術的意義となる.また,これらの材料の新たな知見により,例えば,誘電率変化を捉えることで可能となる非破壊センシング技術(農作物の自動生育モニタリング,バイタルセンシング,それらを効率よく実現する電波吸収体)の実現に向けた材料科学への貢献が期待できる.これはSociety5.0で掲げられている農業高度化や超高齢化社会の支援を可能とする技術でもあり,社会的意義は高いと考えられる.
