Summary:
Thus, we have actually proven that a multilayered periodic structure can never produce a left handed field. Note further, that the evanescent waves are attenuated (as their name indicates) not amplified as they go through the periodic structure. More specifically, EM-waves originate on electric and/or magnetic conductors. They do not suddenly start behaving "strange" between the elements. For more detail, study the theory of periodic structures in [15]. This does not contradict Veselago [1] who made no claims about the existence of materials with negative μ and ε.
