“…The phenomenon of tunneling of electromagnetic waves through opaque layers has always been a fascinating and somehow counterintuitive subject. Tunneling structures based on an extremely high negative permittivity layer coated by high positive permittivity layers [1], a negative permittivity slab sandwiched between birefringence layers [2], conjugate matched pair of negative permittivity and negative permeability slabs [3], a negative permittivity slab paired with a double-positive uniaxial slab [4], and permittivity-near-zero bi-layers [5] have been reported. Recently, it was revealed that the phenomenon of electromagnetic wave tunneling can happen through electrically long distances [6].…”

We show that electromagnetic plane waves can be fully "teleported" through thin, nearly fully reflective sheets, assisted by a pair of parity-time-symmetric lossy and active sheets in front and behind the screen. The proposed structure is able to almost perfectly absorb incident waves over a wide range of frequency and incidence angles, while waves having a specific frequency and incidence angle are replicated behind the structure in sync with the input signal. It is shown that the proposed structure can be designed to teleport waves at any desired frequency and incidence angle. Furthermore, we generalize the proposed concept to the case of teleportation of electromagnetic waves over electrically long distances, enabling full absorption at one surface and the synthesis of the same signal at another point located electrically far away from the first surface. The physical principle behind this selective teleportation is discussed, and similarities and differences with tunneling and cloaking concepts based on PT -symmetry are investigated. From the application point of view, the proposed structure works as an extremely selective filter, both in frequency and spatial domains.

“…The physical origins are usually ascribed to the excitation of surface plasmons (SPs) [1]- [3] (or spoof SPs (SSPs) for highly conducting structure [4]), and/or the Fabry-Pérot (FP)-like resonances in the defects [5]- [7]. Additional mechanism to tunnel light by the high magnetic field concentrated around the metallic films is also evidenced [8], [9]. However, SMG usually supports narrowband transmission because of its resonant nature.…”

We present a new mechanism to realize broadband transmission (BT) at near infrared in a dual-layer metallic-silver-grating structure with a silicon nitride dielectric spacer. The physical mechanism is ascribed to thepartial degeneracy between the firstorder magnetic polariton ðMP 1 Þ mode supported in the thin dielectric spacer and the Fabry-Pérot-like resonant modes supported in the gratings' slits. With parameters optimized, high transmittance up to 85% with full-width-at-half-maximum bandwidth of 64% near 1.9 m can be realized for TM-polarized light. Moreover, the BT can be maintained in a large range of oblique incident angles from 0 to 30 . In another word, the BT is capable of not only collimated beams but also noncollimated incident lights. Moreover, the high-transmission window can be tuned in the IR spectrum region by modulating the metallic gratings' thicknesses.

“…[7][8][9][10][11] While for a seamless thin metallic film, only a few attempts have been done to enhance its transmission. 12,13 Recently, a symmetric multiple-layered nanostructure has been demonstrated to achieve broadband transparency for a continuous Ag film. 14 In view of the fabrication, it is quite difficult to make highly symmetric structures on both sides of the Ag film.…”
