Florin Abelès (October 20, 1922 – April 12, 2005) was a French physicist, specialized in optics. In his 1949 doctoral thesis, Abelès developed a transfer-matrix formalism to compute the transmission and reflection of light by thin dielectric layers. When Lyman G. Parratt performed the first x-ray reflectometry experiment in 1954, he developed an equivalent recursion method. Nowadays, Abelès matrices or Parratt recursion are exchangeably used in investigations of multilayers by x-ray reflectometry,

neutron reflectometry Neutron reflectometry is a neutron diffraction technique for measuring the structure of thin films, similar to the often complementary techniques of X-ray reflectivity and ellipsometry. The technique provides valuable information over a wide var ...
