“…3d, and the silver plate by an overdense plasma (i.e., a plasma whose Langmuir (plasma) frequency is higher than the incident wave frequency), Fig. 3e, the same effect appears: the incident electromagnetic wave can be totally absorbed by the plasma (Bliokh et al, 2005;Wang et al, 2006), Fig. 3f, even though both elements act separately as very good mirrors.…”

Superresolution, extraordinary transmission, total absorption, and localization of electromagnetic waves are currently attracting growing attention. These phenomena are related to different physical systems and are usually studied within the context of different, sometimes rather sophisticated, approaches. Remarkably, all these seemingly unrelated phenomena owe their origin to the same underlying physical mechanism -wave interaction with an open resonator. Here we show that it is possible to describe all of these effects in a unified way, mapping each system onto a simple resonator model. Such description provides a thorough understanding of the phenomena, explains all the main features of their complex behavior, and enables to control the system via the resonator parameters: eigenfrequencies, Q-factors, and coupling coefficients.

“…Here Q leak 1 and Q leak 2 are the leakage Q-factors (Q −1 leak = Q −1 leak 1 + Q −1 leak 2 ), which are related to the transmittances T 1 and T 2 of the two barriers by (Bliokh et al, 2005)…”

“…14 To improve absorption of the laser energy, advantage can be taken of surface plasma wave excitation. [15][16][17][18][19][20] Under certain conditions, these waves can be supported by an overdense plasma with a stepwise density profile. 21 Such laser-excited surface plasma waves are localized at the plasma-vacuum interface.…”

Two-dimensional ͑2D͒ particle-in-cell numerical simulations of the interaction between a high-intensity short-pulse p-polarized laser beam and an overdense plasma are presented. It is shown that, under appropriate physical conditions, a surface plasma wave can be resonantly excited by a short-pulse laser wave, leading to strong relativistic electron acceleration together with a dramatic increase, up to 70%, of light absorption by the plasma. Purely 2D effects contribute to enhancement of electron acceleration. It is also found that the angular distribution of the hot electrons is drastically affected by the surface wave. The subsequent ion dynamics is shown to be significantly modified by the surface plasma wave excitation.

“…It is worth noting that in the presence of dissipation, the resonance investigated in our work will lead to an increased energy absorption. This is important for a number of laboratory plasma devices [18,34] and radar applications [35,36]. These studies are left for future work.…”

“…In the present paper, we consider a layer of dense plasma nested between two boundary layers of a material with a dielectric permittivity ε > 1. Such a configuration may occur, for example, in microwave plasma reactors [18]. We show that in this case, the whole structure becomes transparent to the incident wave if the plasma density, the dielectric permittivity of the boundary layers and the width of the boundary layers are chosen appropriately.…”

Abstract-A study of electromagnetic wave propagation in dense plasmas when the wave frequency is below the cut-off frequency is presented. A three-layer symmetric structure consisting of dense plasma nested between two boundary layers is studied analytically and numerically. The permittivity of the dense plasma is negative, while the permittivity of each boundary layer is greater than 1. It is shown that total transmission of an electromagnetic wave can be achieved if an adequate incidence angle, dielectric permittivity of the boundary layers and corresponding boundary layer widths are chosen. It is found that plasma transparency is due to resonance between the evanescent waves in the dense plasma region and the standing waves in the boundary layers. Resonance conditions are derived analytically and the relationship between the corresponding parameters of the problem are studied numerically.
