The first of these is the variable, non-rectilinear propagation of metric and centimetric waves through the lower atmosphere, the range of such waves over the earth's surface often far exceeding ...

IN the wave theory of light, the geometrical laws of optics—rectilinear propagation, reflection and refraction—and other results besides, rest on a single principle. The fundamental postulate ...

Kyocera Corporation (President: Hideo Tanimoto) (TOKYO:6971) has developed a Transmissive Metasurface technology that can redirect wireless network si ...

Terran Orbital Corporation (NYSE: LLAP) (“Terran Orbital” or “the Company”), a global leader in satellite-based solutions primarily serving the aerosp ...

By contrast, rectilinear biphasic defibrillators deliver a positive charge for half of the shock and a negative charge for the rest, requiring less energy (150-200 joules) to restore cardiac rhythm.

The 28 GHz band used in 5G networks, and the higher frequency band being studied for 6G, have a high degree of rectilinear propagation. Signals often cannot reach locations where a direct line of ...
