This study introduces a multidimensional sampling theory, overcoming Nyquist limitations and enhancing metasurface design for advanced optical applications.

A research team has developed a novel multidimensional sampling theory to overcome the limitations of flat optics. The study not only identifies the constraints of conventional sampling theories in ...

The analysis suggests that three key factors should be taken into account, azimuth spectrum aliasing, Doppler centroid ambiguity, and high-order errors. To deal with these challenges, a novel GMTIm ...
