Researchers at the AMOLF institute have created a revolutionary soft robot without electronic components that moves using ...

The beam tilt angle of a rotatable flush-mounted surface-wave antenna mounted on the underside skin of an aircraft varies as the antenna is mechanically scanned in azimuth. This beam tilt-angle ...

Asymmetric transmission or optical-diode behavior have very important applications in information technology, such as directionally-sensitive beam splitting, multiplexing, and optical interconnection.
