Negative_Refraction_Makes_a_Perfect_Lens
Negative refractionEM wavesWave propagationResolution abilityA discussion of a question, studied earlier by Veselago in 1967 and by Pendry in 2000, is given. The question is: can a slab of the material with negative refraction make a perfect lens? Pendry's conclusion was: yes, it can. Our ...

Such structure use an optical resonance to attain negative refraction; this requirement narrows ΔλW and causes high resistive losses. However, realization of a broad ΔλW and low-loss requires that resonance be avoided. Therefore, in this paper, we present vertically-stacked metal-dielectric ...
On the other hand, negative refraction of electromagnetic waves can also result from Bragg scattering effects of photonic crystals, where the effective index is still positive3, 4. Similar to the perfect lens consisting of LHMs, negative refraction in photonic crystals can also lead to a flat ...
Photon-magnon coupling, where electromagnetic waves interact with spin waves, and negative refraction, which bends the direction of electromagnetic waves unnaturally, constitute critical foundations and advancements in the realms of optics, spintronics, and quantum information technology. Here, we explore a...
