The dispersion curves of the surface wave modes obtained from the exact solution and the MoM start from zero frequency as evanescent waves and change to forward waves at a certain frequency, [OMEGA] = 0.
Evanescent wave and distal mode experiments were conducted at 60 [degrees] C for both dyes, and the results are compared in Figs 5 and 6.
The experimental setup arrangement of evanescent wave fiber optic sensor is shown in Figure (4).
If the index of the superlens is exactly minus one and without any loss, the field strength of every evanescent wave is equal at the position of A and A', and therefore the image at A' will be perfect.
Additionally, the manipulation is also feasible for controlling evanescent waves.
A conventional imaging system only transforms propagating components, and loses the decaying evanescent waves when detected in the far field.

A superlens made out of a metamaterial focuses propagating waves and reconstructs evanescent waves arising from the illuminated objects in the same plane to produce an image with sub-wavelength resolution," said co-author Susanne Kehr at the University of Saint Andrews in the UK.
Evanescent waves are formed when sinusoidal waves are internally reflected off an interface at an angle greater than the critical angle so that total internal reflection occurs.
The evanescent field excites a fluorophore localized near the metal surface, which in turn emits evanescent waves, generating surface plasmons at the fluorescence emission frequency.
The nanowires carry light via evanescent waves that envelop the slender filaments.
