Resonant Transparency of a Three-Layer Structure Containing the Dense Plasma Region

“…Thus, no surface mode excitation can occur in the present situation. We have shown that there exists a specific resonance condition, given by Equation (23), at which absolute transparency occurs due to resonance of evanescent modes in the central region and propagating modes in the end regions. Resulting amplification of evanescent modes lead to resonant transmission of the electromagnetic wave through a dense plasma layer.…”

“…Evanescent waves can be amplified in a medium with negative permittivity thus providing energy transport through opaque materials [20][21][22][23]. Typically, amplification is achieved by creating conditions for resonant excitation of surface modes [17,21,22,[24][25][26].…”

Laser interaction with a dielectric block

“…The potentials in Quantum Mechanics (QM) are identifiable with dielectric materials with different refractive indices with which the laser interacts. One of the advantages of this fact is that QM effects, probabilistic in nature and valid for massive particle wave packets, can be reproduced, and the theory tested far easier, with optical analog experiments [5][6][7][8][9][10][11][12].…”
