The theory of electromagnetically induced transparency (EIT) in a plasma [1] is examined in the context of a bounded system via particle simulations. It is found that when boundaries are introduced into the problem, the requirements of causality preclude the transmission of radiation through an overdense plasma as conceived in the original theory. However, a two-frequency laser, or "beatwave", will cascade into a Stokes satellite with a frequency below the cut-off frequency. This can lead to an apparent EIT signature if a specific set of parameters are chosen.
