Near-field coupling between orthogonally twisted bright and dark mode resonances gives rise to sharp Fano-like resonances and electromagnetically induced transparency. We demonstrate that by varying the orientation of the near-field coupled bright and dark metamolecule with respect to the incident electric field, the shape and linewidth of the coupling induced transparency could be easily engineered. This particular aspect of the near-field coupled metamolecules could lead to engineered slow-light devices, narrow bandpass filters and ultrasensitive sensors.
