WebPath loss, or path attenuation, is the reduction in power density ( attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system. This term is commonly used in wireless communications and signal propagation. WebAug 11, 2024 · We demonstrate that a perfect anomalous reflector can be realized as a simple metal pattern on a thin grounded dielectric slab. In this scenario, engineered modulations of the surface reactance ensure the required nonlocal reflections, which are eventually perfectly launched only in the desired direction.
