Core-loss EELS

Current Opinion in Solid State and Materials Science, 1998
Abstract It is now possible to create an atom sized electron beam that can probe the electronic structure of materials on the scale. Electrons passed through an electron spectrometer from such a probe give energy loss spectra that can provide insight on the local chemistry, bonding and electronic structure.

Influence of reflected radiation waves caused by large mode field and large refractive index mismatches on splice loss evaluation between elliptical-hole lattice core holey fibers and conventional fibers [PDF]

, 2013
When the mode field and refractive index mismatches between two spliced fibers are small, the splice loss is generally evaluated by calculating an overlap integral without reflection waves.
