Multifunctional Single-Layer Metasurface for Electromagnetic Wave Manipulations

We report a design of single-layer metasurface with multifunctional control of electromagnetic waves at different frequencies in the microwave range. The metasurface consists of properly arranged and well-tailored metallic helices in a periodic lattice providing a balanced electromagnetic response to the impinging plane waves. The single-layer metasurface performs three main functionalities as a total absorption and polarization conversions in the reflection and transmission regimes while being fully transparent away from the resonance frequencies. The proposed multifunctional metasurface exhibits a great performance and might be a good candidate for the microwave filtering and antenna applications.
