Spot size converters (SSCs) provide an efficient coupling from arrays of optical fibers to photonic integrated circuits (PICs). They reduce the mode field using lithographically defined waveguides ...

This paper presents a circular-polarized gap-waveguide-based compact monopulse array antenna for millimeter-wave tracking applications at Ka-band (29 to 31 GHz). The gap waveguide planar monopulse ...

The smaller the particles, the more worrying they are. Particulate matter measuring 10 micrometers or less in diameter — a fraction of the width of a human hair — is referred to as PM10, and it is ...
