| Outline of Final Research Achievements |
A bi-anisotropic material is characterized by magnetelectric and electromagnetic tensors, which are included in construction relation. Properties of these tensors have been independently discussed so far in microwave-engineering and in condensed-matter physics.
Thus, there remain possibilities where knowledge of one can been transfer to the other and vice versa, resulting in feasible and novel effects. The present study tried to bridge the two subjects, and was found to be effective.
Also as serendipity, we propose dynamical instability to explain a newly discovered phenomenon, wiggling and jump of a coronene nanofiber, by an experimentalist during preliminary stage for future collaboration.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は，従来異なる分野で行われていた類似の題材を，統一的な立場から捉え直し，共通言語や互いの対応付けを明確にすることで，両者の知見の相互乗り入れを可能にして，将来的な新規現象の開拓の素地を作ろうとするものでった．今回得られた結果は，両分野において有用であると考えられる．
また，分野横断型の研究は，準備に大きな労力を要求されることと，短期的な成果を得ることが難しい事から敬遠される傾向にあるが，この取り組みは，新たな研究シーズを見いだすために有効であると思われる．
