In order to solve the problem that performance of traditional localization methods for mixed near-field sources (NFSs) and far-field (FFSs) degrades under impulsive noise, a robust novel method is proposed. After eliminating impacts noise by weighted outlier filter, direction arrivals (DOAs) FFSs can be estimated multiple signal classification (MUSIC) spectral peaks search. Based on DOAs inform...

For mixed far-field (FF) and near-field (NF) source localization, most existing algorithms are developed for the scenario where number of available data samples ${N}$ is much larger than sensors notation="LaTeX">${M}$ . Different from...

The metasurface is a platform with small footprint and abundant functionalities. With propagation phase geometric phase, polarization multiplexing possible. However, different response behaviors of to wavelength have not been fully employed widen the capabilities metasurfaces. Here, we theoretically demonstrate that metasurfaces can achieve near-field far-field decoupling same at two wavelength...
