Сравнение методов расчета распространения рентгеновского излучения через ДОЭ в параксиальной области

Сравнение методов расчета распространения рентгеновского излучения через ДОЭ в параксиальной области

Abstract

В статье приведены результаты различных вариантов моделирования распространения света после прохождения через зонную пластинку из меди и кремния для рентгеновского излучения. Моделирование проводилось с помощью расчета одномерного преобразования Френеля, одномерного непараксиального распространения (через угловой спектр), двумерного интеграла Релея-Зоммерфельда, RSoft BeamProp из пакета FullWave, производитель RSoft Design Group, США. Показано, что первые три метода дают очень близкие результаты. Результат, полученный с помощью программы BeamProp, отличается приблизительно на 10%.

A results of modeling of X radiation propagation through a zone plate by different calculating methods are described. A zone plate made of cuprum and silicon is considered. Modeling was calculated by 1D Fresnel conversion, 1D light non paraxial distribution, 2D integral Rayleight Zommerfeld, RSoft BeamProp from FullWave program, designed by RSoft Design Group, USA. It is shown, that first three methods have results very close each other. The result of modeling by BeamProp, differs about 10%.
