A metamaterial structure with a unit cell made of a metallic slab with two short and two long cut-wires is introduced in a computational work, simulating electromagnetically induced transparency (EIT) at microwave wavelengths. The structure introduced is flexible in applications and, by suitable manipulation of geometrical parameters, can be utilized for different practical purposes. It is shown that the structure can operate as a microwave sensor in a relatively wide temperature range around the room temperature. The sensitivity and figure of merit (FOM) of the sensor is relatively high, with the maximum value of the FOM calculated to be 24. By suitable geometrical tailoring, it is also shown that the proposed structure has the potential to be used in slow light devices as well, with a large value, 436, achieved for the group index. Effects of the slab height on the group index is also studied.
