We present a classical analog of electromagnetically induced transparency (EIT). In a system of just two coupled harmonic oscillators subject to a harmonic driving force, we reproduce the phenomenology observed in EIT. We also describe a simple experiment with two linearly coupled RLC circuits which can be incorporated into an undergraduate laboratory.

As discussed, the induced transparency results from the existence of two possible paths for the absorption of the probe energy to excite the oscillation of particle 1. We can see these paths in Eq. (5) by rewriting it as a superposition of the normal modes of oscillation of the coupled oscillators.
