We discuss the propagation of electromagnetic waves through a one-dimensional periodic array of bilayers with metal inclusions. We show that the nonlocality of metal conductivity leads to the emergence of the fundamental collisionless Landau damping. It cannot be neglected, not only when prevailing over ordinary collision damping, but even when these two kinds of electromagnetic absorption are ...

(2) where 〈〈· · ·〉〉means the thermal average with respect to the medium with temperature T and baryon density n; Jμ is the electromagnetic current operator. Also the real photon emission rate is related to ImΠμν . Therefore, the electromagnetic probes are sensitive to the medium properties. Since the absorption probability of such probes, once emitted, is small they carry information on the ful...

Abstract. We show that the mode corresponding to the point of essential spectrum of the electromagnetic scattering operator is a vector-valued distribution representing the square root of the three-dimensional Dirac’s delta function. An explicit expression for this singular mode in terms of the Weyl sequence is provided and analyzed. An essential resonance thus leads to a perfect localization (...

This paper presents electromagnetic energy absorption in the homogeneous and layered human body models due to body-worn UWB antennas, at frequencies of 3, 6 and 8 GHz. Typical small planar UWB antennas are used in this study: printed UWB disc monopole and UWB slot antenna. Distances of 2, 5 and 10 mm (reactive near-field region) between antennas and human body were chosen, approximating realist...

The possibility of compensating absorption in negative-index metamaterials (NIMs) doped by resonant nonlinear-optical centers is shown. The role of quantum interference and the extraordinary properties of four-wave parametric amplification of counterpropagating electromagnetic waves in NIMs are discussed.

Metamaterials (MMs) with artificial structures have extraordinary physical properties that cannot be found in traditional materials. MMs electromagnetic wave absorption (MMAs) can prepared through the structural design and arrangement of unit special properties. These at subwavelength scale are fundamental for MMAs to surpass performance limits bulk materials, so matching manufacturing processe...
