By spatially arranging magnetochiral metamolecules possessing both magnetization and chirality, it is possible to mimic multipole structures that determine microscopic electronic responses in the bulk. In this presentation, we fabricated metamolecules by sandwiching a magnetized ferrite plate between copper double-Z structures and arranged them with symmetry considerations to experimentally investigate the microwave response originating from the multipole structures.
