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...

The terms near field and far field have similar, but somewhat different meanings depending on the context. Various cases are discussed in the following sections. Normally, there is no precisely defined boundary for the near or far field.
One example discloses a combination near-field and far-field antenna configured to be coupled to a conductive host surface, including: a first feed point configured to be coupled to a far-field transceiver; a second feed point configured to be coupled to a near-field transceiver; a first ...
