In systems with broken space-time inversion symmetry, nonreciprocal electromagnetic responses, such as directional birefringence for unpolarized light, are induced. Dual-resonator systems exhibit intriguing phenomena such as bound states in the continuum (BICs) and antiresonances, and introducing magneticmaterials is expected to further enhance their functionality. In this study, we incorporated a magnetic material into a meta-molecule consisting of a split-ring resonator and a crossed resonator. When fed by a microstrip line, the metamolecule exhibits one-way transparency, with the transmittance difference between the forward and backward directions reaching 0.68.
