A reconfigurable metamaterial analog electromagnetically-induced-transparency-like (EIT-like) effect is theoretically and numerically demonstrated in this paper. The unit cell is composed of a stimulated circular loop element and an unstimulated arc slot element, which are both constructed by semiconductor. The interaction between the two elements of the unit cell leads to a transparency window, resembling a special quantum optical phenomenon as electromagnetic (EM) induced transparency. The proposed designs can realize a continuously tunable EIT-like effect in a broad frequency range from 2.2 GHz to 3.6 GHz by changing the arc slot angle, while the number of EIT-like transmission windows can be configured by increasing the number of arc slots. This scheme which is constructed by solid state plasma (SSP) metamaterial provides an alternative way to realize the tunable plasmonic sensing and make new kinds of reconfigurable devices.

AbstractWe implement slow-light under electromagnetically induced transparency condition to measure the motion of cold atoms in an optical lattice undergoing Bloch oscillation. The motion of atoms is mapped out through the phase shift of light without perturbing the external and internal state of the atoms. Our results can be used to construct a continuous motional sensor of cold atoms.
