Ka-band metasurface antennas, with their low-cost, low-profile design and superior beam-steering capabilities, show significant potential in the field of satellite communications. However, the constraints of limited satellite resources and significant atmospheric losses at Ka-band frequencies require these antennas to achieve wide-angle beam scanning capabilities and high antenna gain, adding considerable complexity to their design.Ka-band metasurface antennas, with their low-cost, low-profile design and superior beam-steering capabilities, show significant potential in the field of satellite communications.

The Hong Kong-Zhuhai-Macao Bridge is a cross-sea bridge connecting Hong Kong, Zhuhai, and Macao, spanning 55 kilometers. The bridge features a “bridge-island-tunnel” design, including a 6.7-kilometer undersea tunnel and two artificial islands, with a total investment of approximately 120 billion yuan.The Hong Kong-Zhuhai-Macao Bridge is a cross-sea bridge connecting Hong Kong, Zhuhai, and Macao, spanning 55 kilometers.

The 2024 Nobel Prizes in physics and chemistry have given us a glimpse of the future of science. Artificial intelligence (AI) was central to the discoveries honored by both awards. You have to wonder what Alfred Nobel, who founded the prizes, would think of it all.The 2024 Nobel Prizes in physics and chemistry have given us a glimpse of the future of science.

Artificial Intelligence has learned to master language, generate art, and even beat grandmasters at chess. But can it crack the code of abstract reasoning—those tricky visual puzzles that leave humans scratching their heads?Artificial Intelligence has learned to master language, generate art, and even beat grandmasters at chess.
