Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...
Research Significance：With the rapid development of modern wireless systems such as radar and communications, there is an urgent need for the integrated development of multi-functional RF antennas.
Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...
Electronically steered arrays are essential in next-gen satellite constellations. Fragmented-aperture technology overcomes limitations of traditional monolithic radiating elements. Aperture efficiency ...
Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
Engineers at Rice and Northwestern universities in the US say that they have built a prototype lens-free camera capable of high-resolution imaging in the visible range. Similar in principle to the ...
