在光学中，近场（Near Field）和远场（Far Field）是描述光波传播时不同位置的两种特定区域。近场（Ne...

近场光学研究非辐射模式的非均匀场及其与物质的相互作用，通常位于辐射源区域或折射率/介电常数非均匀的位置界面。近场定义模糊，不同研究领域有各自界定。一般认为，辐射源附近或倏逝波不可忽略的区域属于近场。在电磁场增强、偶极子发射源或局域场增强超分辨等领域，通常将[公式]量级范围视为近场。研...

Near field is the optical field close to an object or beam focus; far field is at large distances, with context-dependent meanings.
Experimental and Modelling studies have been used to investigate the biogeochemical processes occurring at the interface zone between the near-field and far-field of the Drigg Low-Level radioactive Waste (LLW) trenches. These have led to a conceptual model of interface biogeochemistry, which has su...
This means the boundary between the near field and far field should move further away from the source. Finally, the boundaries are defined in terms of R-wave length ( λ R ) and Poisson ratio of the ground ( gv ). For the case of a point load, the boundary is located at the ...
