“…Multilayer dielectric structures are placed in the laser aperture for mode selection [3]. Metaldielectric layers in a photonic nanostructure can act as a wide-aperture omnidirectional insulator [4]. A hybrid metal-dielectric nano-aperture antenna can be used to enhance surface fluorescence [5].…”

Infinite linear waveguide antenna array with metal-dielectric structures in the "floquet channel"

An electrodynamics calculation is performed for an infinite waveguide antenna array in the form of open ends of waveguides, in the near zone of which a metal-dielectric structure is located. This metal-dielectric structure is located in the "Floquet channels" and is a combination of a dielectric coating over the antenna array and horns. In this case, the horns are not a continuation of the waveguides, but are located at some distance from them. The space between the waveguides and the horns is filled with a dielectric. A system of equations that allows calculating the reflection coefficients of incident waves in waveguides is obtained.
