Two-dimensional (2D) semiconductors, materials that can conduct electricity and are only a few atoms thick, are promising ...

This paper proposes a hybrid driven MUSIC two-dimensional direction finding algorithm (DM-MUSIC) applied to a uniform circular array (UCA) to address the problem of traditional multi signal ...

This article presents a novel design of a 360° azimuthal plane pattern reconfigurable antenna (PRA) based on a substrate integrated waveguide (SIW) technique for 5G NR (n258) millimeter-wave (mmWave) ...

The puzzle presents three patterns and asks you to predict the next shape for a square. By analyzing the circular pattern, you can identify that Option D is most similar to the previous shapes.
