چکیده
The theory of electromagnetically induced transparency ~EIT! in a plasma @S. E. Harris, Phys. Rev. Lett. 77, 5357 ~1996!# is examined in the context of a bounded system. It is found via particle simulations that an overdense plasma slab reflects short pulses even in the presence of an EIT passband. 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. © 2000 American Institute of Physics. @S1070-664X~00!00507-3#

On the possibility of electromagnetically induced transparency in a plasma. I. Infinite plasma
The theory of electromagnetically induced transparency ~EIT! in a plasma @S. E. Harris, Phys. Rev. Lett. 77, 5357 ~1996!# is examined in the context of an infinite system. A new dispersion relation is derived which accounts for relativistic effects in an overdense plasma. Several branches of the dispersion relation are plotted and discussed. Particle simulations are used to confirm the findings...
متن کاملElectromagnetically Induced Transparency in a Bounded Plasma and its Relation to Beatwave Physics
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”, ...
متن کاملThe Effect of Antenna Movement and Material Properties on Electromagnetically Induced Transparency in a Two-Dimensional Metamaterials
Increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (EIT) and similar phenomena i...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
متن کاملElectromagnetically Induced Transparency in an Ideal Plasma.
A process analogous to electromagnetically induced transparency in atoms is described for an ideal plasma. Two electromagnetic fields whose frequency difference is near, but not equal, to the plasma frequency will drive a longitudinal plasma oscillation whose contribution to the current density opposes the current density produced by either field, if alone. This creates a passband at frequencie...
