“…Shen et al [15] remarked that in the explanatory figure ( Figure 3) in [7] the direction of the wave vector of the refracted wave in the left-handed medium is incorrectly indicated. This same figure was also reproduced in [5,6,[18][19][20]. In the figure in [21] corresponding to Figure 3, the directions of both the wave vector and the Umov-Poynting vector are indicated, but it is not indicated for which of them Snell's law formula applies.…”

Generalized representations of the refraction law are obtained for electromagnetic waves at the interface of transparent isotropic media with positive and/or negative permittivity and permeability.The phenomenon of reversed (negative) refraction has been well known among physicists for a long time. Sir Horace Lamb [1], responding to the model proposed by Lord Rayleigh (John Strutt) of a device in the form of a clamped wire subjected to tension and torsion [2], conjectured that in a cylindrical wire under certain conditions vibrations can also arise having group velocity that is negative with respect to the phase velocity. He considered the passage of a one-dimensional wave from a segment of the wire with the usual vibrational regime to a segment with the anomalous regime and was the first to observe that the transmitted wave should have a phase velocity oppositely directed relative to the phase velocity of the wave incident on the inhomogeneity. That same year, A. Schuster noticed and graphically elucidated [3, p. 317, Fig. 179] the curious result of the negative angle of the refracted light wave in a medium with opposed phase and group velocities, which was necessary to ensure unidirectional translation of the intersection lines of the wave fronts of the incident and refracted wave with the boundary of the two media. In optics and electrodynamics the simplest isotropic medium, at the boundary with which negative refraction can take place, is a magnetodielectric with negative values of its electric permittivity ( 0   ) and magnetic permeability ( 0   ), which was first pointed out by D. V. Sivukhin [4] and V. G. Veselago [5-7]. Negative refraction is most graphically manifested, for example, for oblique incidence of a plane wave from vacuum ( 0    and 0    ) into anti-vacuum (this term was proposed in [8], 0    and 0    ), where 0 and 0  are the electric and magnetic constants. In this case, reflection of a wave from the interface does not take place, but the initial direction of propagation as the wave propagates into the second medium is changed to the direction of the wave vector of the absent reflected wave. Here the refracted wave, being a backward wave, transfers energy in accordance with the radiation condition from the interface into the periphery of the second medium. References [9][10][11] are dedicated to historical and other aspects of the electrodynamics of media with backward waves and their discussion in the literature. A modification of Snell's refraction law was proposed in [5][6][7] relevant to the interface with a hypothetical lefthanded medium with both  and  negative, presaging the introduction of the new concept of a negative refractive index. After the first experimental confirmation of the phenomenon of negative refraction for microwaves [12] and the appearance of the concept of electromagnetic metamaterials, the English-language version [7] of Veselago's paper [6] acquired some fame and became widely cited and much in demand. Despite some doubts and objections [13][1...

“…It follow from formulas (18) and (19), in particular, that at the interface of two left-handed media refraction takes place in the same way as in the case of two right-handed media. This property was already noted earlier in [26].…”

“…Now there comes the problem of describing these incident beams along a NRI medium. For a plane wave along +z, for example, one must assume exp(+i|k m |r cos θ) in order not to contradict causality [29], thus reinforcing the negative phase velocity characteristic. Notice that this consideration about the phase of the incident wave was not taken into account in the geometrical optics due to the fact that a ray is assumed, by definition, to have zero wavelength [40].…”

Using the revised plane wave method, we calculated the photonic band structure (PBS) considering TE polarization of a square 2D photonic crystal made of rectangular metallic rods embedded in air. In case of square rods and comparing different plasma frequencies, we found a characteristic band distribution related with the existence of localized plasmons on the rod surfaces, and also we found that this type of rod shape contributes to a high concentration of the electromagnetic field close to the rod corners. Considering rectangular rods and varying one of the sides of the rods, we found a PBS that presents a reorganization of the bands in comparing with the low dispersion present in the square rod case, related with a high localization of the radiation on the rod surfaces.
