Molding the flow of light—whether confined to localized regions or propagating in free space—remains crucial for modern ...

At that, the complexity of the sensor is greatly reduced, since a small antenna aperture is employed and synthetically expanded. While SAR is frequently applied to high-end microwave radar imaging, it ...

The key to this method is in fiber-optic cables that react to disturbances underground. With a system to monitor cables, scientists are tapping into unseen volcanic data like never before. Iceland's ...

Add a description, image, and links to the high-numerical-aperture topic page so that developers can more easily learn about it.
