A research team at POSTECH has developed a novel multidimensional sampling theory to overcome the limitations of flat optics.

Finally, methods applicable to large spectrum of civil structures ... handling and storage of data; sampling frequency and aliasing; system identification and modal analysis. 8) Global and integrity ...

The NVIDIA RTX 5090 is the most powerful consumer GPU ever made, but its $2,000 price tag makes it a luxury for only the most ...

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 ...

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