DOI: 10.1007/s10773-021-04914-w
Abstract: We propose a quasi-M-type atomic system for realizing the electromagnetically induced polarization grating. The results show that, due to the introduced microwave fields, the first-order diffraction efficiency of the probe field can be increased remarkably.… read more here.

DOI: 10.1016/j.jappgeo.2018.09.030
Abstract: Abstract Spectral induced polarization (SIP) measurement requires synchronous current acquisition and real-timetransmission devices or precise phase-measuring apparatus. To carry out SIP investigations in the absence of these auxiliary devices, a new SIP measurement has been… read more here.
