Features of surface Bessel plasmon-polaritons in optical anisotropic hyperbolic metamaterials

“…At present, the attention of many researchers is turned to quasi-nondiffracting light fields. Among them, the Bessel light beams (BLBs) occupy a special place, having a divergence in the axial region significantly smaller than that of traditional (e.g., Gaussian) beams, as well as the ability to self-reconstruct the wavefront [24][25][26][27][28][29]. However, the evanescent BLBs investigated in works [24][25][26][27][28][29] have a significant disadvantage: they are weak.…”

Cylindrically symmetric surface electromagnetic waves

“…The geometry of metal film was a plane in the all investigations listed above. A simple setup for generating TM-polarized evanescent Bessel beams [7,8] is proposed in ref. [9].…”

Generation of Bessel Surface Plasmon Polaritons in a Finite-Thickness Metal Film

“…But the evanescent BLBs investigated before [24][25][26][27][28][29] possess an essential disadvantage, namely, they are weak, which causes the necessity of application of strong laser fields for their generation. One of the ways of taking Bessel light field advantages for microscopy is the formation of Bessel surface plasmon polaritons (BSPPs).…”

“…A more detailed theory of evanescent Bessel beams is presented in [24][25][26][27][28][29]. These beams exponentially decay while moving off the surface but retain their original transversal shape.…”
