We present a terahertz classical analog of electromagnetically induced transparency by means of single-layer metamaterial consisting of two closed square ring. The narrow transparency peak is mainly caused by the excitation of antiparallel currents in different rings. Because of symmetry configuration, the designed metamaterial possesses stable polarization-independent and wide-angle transmission spectral features. Moreover, the design has a simple structure ideally suitable for the current planar micro- and nano-fabrications.
