We demonstrate that the presence of a (gyro)magnetic substrate can produce an analog of electromagnetically induced transparency in Fano-resonant meta-molecules. The simplest implementation of such gyromagnetically induced transparency (GIT) in a meta-surface, comprised of an array of resonant antenna pairs placed on a gyromagnetic substrate and illuminated by a normally incident electromagnetic wave, is analyzed. Time reversal and spatial inversion symmetry breaking introduced by the DC magnetization makes meta-molecules bi-anisotropic. This causes Fano interference between the otherwise uncoupled symmetric and anti-symmetric resonances of the meta-molecules giving rise to a sharp transmission peak through the otherwise reflective meta-surface. We show that, for an oblique wave incidence, one-way GIT can be achieved by the combination of spatial dispersion and gyromagnetic effect. These theoretically predicted phenomena pave the way to nonreciprocal switches and isolators that can be dynamically controlled by electric currents.The concept of symmetry pervades modern physics [ 1,2]. Through the conservation laws derived from various symmetries, high-level restrictions and selection rules can be derived for a variety of physical systems without any need for detailed investigations of their specific properties. Electromagnetic (EM) metamaterials [ 3,4,5] and, more specifically, Fano-resonant [ 6] metamaterials and meta-surfaces (FMs) [ 7,8,9,10,11,12,13,14,15] [ 20,21,22], dynamic tuning [ 23,24,25,26,27,28,25], and sensing and biosensing [ 29,30,31,32,33]. The spatial symmetries of electric charge distribution on the metamaterial's surface determine whether the EM resonance is "bright" (radiatively coupled to) or "dark" (radiatively de-coupled from) the EM continuum. As we demonstrate in this letter, other symmetries and their breaking can also be crucial to determine the properties of EM resonances and enable their mutual coupling, which in turn can give rise to EM Fano interferences.We consider a meta-surface formed by a two-dimensional array of double-antenna metamolecules [ 34] [ Fig.1(a)]. Such meta-molecules support two low-frequency resonances formed by hybridization of the dipolar modes of the individual antennas that have distinct symmetric and anti-symmetric charge/current distributions responsible for their strongly disparate radiative coupling. The scattering of light by the symmetric mode is dominated by the electric dipolar moment of the meta-molecules ( ) along the y-direction, leading to its strong radiative coupling and its "bright" character. The anti-symmetric mode, in contrast, is dominated by the magnetic dipolar ( ) and electric quadrupolar ( ) moments, leading to its "darkness", i.e. its complete decoupling from the normally incident EM wave [see Fig.1(b)]. Fano interference arises from the coupling between the symmetric and anti-symmetric resonances, which are a consequence of
