Coded aperture imaging (CAI) is an innovative detection method that employs a patterned mask to encode incoming radiation. The encoded signal is subsequently decoded to reconstruct the spatial ...

The aperture mirror structure enhances cooling as its geometry brings into play both the emissivity of the radiative surface and the emissivity of the atmosphere. In a world where rising temperatures ...

Portable radiation imaging systems are making nuclear decontamination and decommissioning tasks less expensive, quicker and safer for workers, as Victoria Anderson Matthew explains Ready for ...

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.

A multileaf collimator (MLC) for radiosurgery from Varian Medical Systems, Palo Alto, Calif., contains up to 120 tungsten slats controlled by miniature motors. The slats block the path of X-rays, ...
