| Popis: |
High-index dielectric mechanical pieces constitute an important source of signal losses in radio frequency systems due to scattering effects. In this study, we propose to camouflage a dielectric scatterer by tuning it with buried metasurfaces. The impact of a high-index dielectric scatterer with respect to a low-index dielectric reference is defined in terms of its induced field ratio (IFR). The IFR of the scatterer can be controlled and minimized via the geometric parameters of the buried metasurfaces’ elements. Full-wave simulations are carried out at 4 GHz and the obtained results validate camouflaging of a dielectric scatterer. Metasurface-tuning is an easily implementable, frequency transposable solution to camouflage non-transparent, dielectric mechanical pieces in radio frequency systems. |
