| Popis: | Electromagnetically induced transmission (EIT) in THz domain is studied in Dolmen structures. The effect of dipole in exciting the otherwise dark quadrupole mode and the interaction of a 2nd dipole in controlling the EIT peak are studied. We show broad EIT peak in Dolmen as well as two EIT peaks and vanishing of EIT peak by varying the position of a 2nd dipole to form a ring like structure. |
