Phys.org  October 11, 2024 Researchers in Australia developed a novel approach for enhancing signal radiation patterns in optical wireless networks utilizing a planar optical aperture incorporated with infrared radiative element clusters to optimize signal radiation patterns through selective cluster excitation. They used dual carrier wavelength approach, leveraging an effectively large carrier wavelength for the system to avoid grating lobes occurrence due to distributed clusters. They used optimization-based algorithm to ensure optimized signal reception at the specific receiver location. Using simulations, they demonstrated the behavior of parameters like side lobe level, focal spot area, and power efficiency within the focal spot […]
