Magnetically Induced Transparency in Classical Magnetized Plasma

Magnetically induced transmission in plasma is a classical analog to the electromagnetically induced transparency in atomic systems. We report the first demonstration of magnetically induced transmission in opaque magnetized plasma. The transmission of radiation through axially magnetized plasma is obtained by applying an additional one-dimensional transverse spatial periodic magnetic field.

The transverse-periodic magnetic field uncouples the right-hand electromagnetic wave from interacting with plasma electrons, rendering the plasma band-stop transparent. This provides means to control the extent of absorption of electromagnetic radiation in magnetized plasma. Moreover, our experiments confirm this prediction and the existence of this classical analog to atomic electromagnetic induced transparency, and clear the way to slow light, non-diffraction and storage under magnetically induced transparency conditions.


Dr. Gad received his Ph.D. in physics from the Technion – Israel Institute of Technology, Haifa, Israel in 2012. His paper, "Observation of Magnetically Induced Transparency in a Classical Magnetized Plasma" was selected as PRL editor choice and was highlighted with synopsis in physics. He is currently a MITACS Postdoctoral Fellow at the University of Toronto in Prof. Levi’s Biophotonics group. His current research interests include photonic nano-structures for biosensing, EM mode manipulation via hybrid metal-dielectric nano-structures, advanced methods for particle acceleration in nano-structures, etc.
