Web26. máj 2024 · First, we present a metasurface to modulate the reflected EM wavefronts without the transmitted modulations as shown in Figure 4a, in which all transmitted phases behave as 0′ and the reflected beam is designed to generate at θ = 30° and ϕ = 0°. The coding patterns of reflection and transmission are presented in Figure 4c,d. WebThe results show that some excellent wavefront manipulations are demonstrated with the phase array by using acoustic metasurface such as anomalous reflection and sub-wavelength flat focusing. The design may offer a path for acoustic manipulation and promote the potential applications of acoustic metasurface in low frequency noise control …
Web14. apr 2024 · The effective modulation of acoustic fields is the most important property of acoustic metasurfaces. The realization of full-space wavefront control can significantly enhance the functionality of metasurfaces; however, the existing solutions to this problem are limited by the coupled modulations of the transmitted and reflected wavefronts. In … WebOptical Windows are flat, optically transparent plates that are typically designed to maximize transmission in a specified wavelength range, while minimizing reflection and absorption. …
