WebApr 11, 2024 · 1.Introduction. Intense scattering occurs as the light propagates through biological tissues, smoke, ground glass, or other scattering media. In such cases, it is tough for the conventional optical camera to capture the image of the object due to the distortion of the light field [1].However, the information about the object is still in the distorted light … WebElectromagnetic wave propagation and scattering in rain and other hydrometeors ... various multiple or incoherent scattering effects on copolar and cross-polar signals, pulse shape, channel transfer characteristics, etc. The aim of this review is to provide fundamental background informations on the interactions between hydrometeors and radio ...

WebApr 10, 2024 · Tsunami Propagation. Once generated, tsunamis radiate outward in all directions from their source. Unlike wind waves that affect just the surface of the ocean, tsunamis propagate (move) through the entire depth of the ocean, from the surface to the floor. Large tsunamis can even move across entire oceans. Tsunamis move at great … WebApr 12, 2024 · As a result, one-way propagation of a traveling-wave mode can be obtained in the microcavity, ensuring the formation of the ES (36, 37). The microlaser system is robust because the formation of the ES is insensitive to fabrication errors. ... which may not identical with the gain of the laser due to the incoherent property of PL.
