Hi, I have a simple question. I have a bilayer (A & B) material with 2mm each thickness, and I want to calculate X-ray absorption final intensity. The layers have different properties. If top layer is A and Bottom is B and incident x-ray is at A, the final intensity that I will have, will that be similar if I have B as top layer and A as bottom layer and the incident x-ray is at B. I mean interchanging the layers whether effects the final intensity or not. It would be a great help for me if anyone could explain. Thanks in advance.
Will be no effect of the order A and B. You could easly check it by using the following equation: I = I0 e-kd there k - is absorption coeff. and d - thickness.
Thanks Penkov, one question, for bilayer, is the eqn for final intensity after will be I=Io exp-kd1.exp-kd2 where d1 d2 are two thicknesses. So, will that be just adding another exponent value of a new layer for the final intensity? Thanks for the Answer. Thumbs Up!!
Sorry the k would be k1 and k2 as two materials have different properties. Thanks in advance
Yes, it will be just multiplication of two exponents with k1 and k2
