Fazovye I Amplitudnye Svoystva Mnogosloynykh Rentgenovskikh Zerkal: Fluktuatsii, Fazovrashchatel'nye Svoystva, Effekt Goosa-khenkhen, Trinarnye Struktury Mariya Barysheva Russian edition

Rabota posvyashchena teoreticheskim issledovaniyam v oblasti mnogosloynoy rentgenovskoy optiki. V ee ramkakh izucheno vliyanie struktury mnogosloynykh rentgenoopticheskikh elementov na fazovye i amplitudnye kharakteristiki volnovogo polya. V chastnosti, na osnove protsedury Fokkera-Planka proanalizirovano vliyanie fluktuatsiy tolshchin sloev rentgenovskikh zerkal na ikh otrazhatel'nye kharakteristiki i prodemonstrirovano nalichie naibolee kritichnykh k vliyaniyu fluktuatsiy oblastey. Obsuzhdayutsya usloviya dlya polucheniya nailuchshikh fazovrashchatel'nykh svoystv mnogosloynykh elementov. Uchet vliyaniya strukturnykh defektov (fluktuatsiy i postoyannykh ukhodov periodov) pozvolil ob"yasnit' eksperimental'no nablyudaemyy znachitel'nyy razbros polyarizatsionnykh i fazovrashchatel'nykh svoystv mnogosloynykh elementov, prakticheski identichnykh s tochki zreniya otrazheniya. Izucheno iskazhenie i smeshchenie (analog effekta Goosa-Khenkhen) volnovykh paketov, vzaimodeystvuyushchikh s mnogosloynoy strukturoy vblizi breggovskogo rezonansa. Proveden analiz trinarnykh zerkal, dlya kotorykh pokazana vozmozhnost' polucheniya koeffitsientov otrazheniya, bol'shikh po sravneniyu so standartnymi binarnymi.
