Abstract: Single and double electromagnetically induced transparency EIT in a medium,consisting of four-level atoms in the inverted-Y configuration, are discussedusing mechanical and electrical analogies. A three coupled spring-mass systemsubject to damping and driven by an external force is used to represent thefour-level atom mechanically. The equations of motion of this system are solvedanalytically, which revealed single and double EIT. On the other hand, threecoupled RLC circuits are used, as the electrical analog, to explore andexperimentally demonstrate single and double EIT. The simplicity of these twomodels makes this experiment appropriate for undergraduate students and easy toincorporate into a college physics laboratory.
