  In the present paper we have discussed in detail electromagnetically induced
transparency and signal storing in the case of one signal pulses propagating in
a classical electric medium resembling this of four-level atoms in the tripod
configuration. Our theoretical results confirm recently observed dependence of
transparency windows position on coupling parameters. In the process of storing
the pulse energy is confined inside the metamaterial as electric charge
oscillations and after required time it is possible to switch the control
fields on again and to release the trapped signal. By manipulating the driving
fields one can thus control the parameters of the released signal and even to
divide it on demand into arbitrary parts.
