Abstract

We present a demonstration of electromagnetically induced transparency (EIT) in magnetized plasmas by means of experiment and numerical simulation. EIT in magnetized plasmas is a phenomenon by which a plasma-absorbing electron cyclotron wave is rendered transparent by a pump wave, which is a classical analog to conventional quantum EIT although the plasma EIT is not a quantum-mechanics-based phenomenon. This paper describes an attempt to identify plasma oscillations excited by the mode coupling of a pump wave and a probe wave, which is a key mechanism for achieving magnetized plasma EIT, by an experiment and a particle-in-cell (PIC) simulation. A preliminary result of the longitudinal electric field measurement indicates an enhancement of the plasma oscillation in the vicinity of the beat frequency between the probe and pump waves. Also the PIC calculation, which simulated the real experiment, shows a plasma oscillation excited by the mode coupling between the probe and pump waves in the magnetized plasma EIT, showing agreement with theory and experiment.
