(a) Scheme of the multilayer with the microhole that can be obtained with the laser ablation method (one of the pixels in the case of the phase-only binary nanohologram). The rays reflected from the multilayer are denoted by numbers 1 and 2 (the incident wave is not shown). D is the hole diameter. (b) Geometry of the corresponding electromagnetic boundary problems. The multilayer includes additional (protective, spacer) “conventional” layers and the main layer and optically thick substrate which electromagnetic properties can correspond to ENZ MMs. E in1,2 and E r1,2 are the fields of the incident and reflected waves.
