Homework Statement At a wavelength of 400nm, the semiconductor ZnSe has a complex refractive index n= 3.0+0.32i A) If 400nm is incidient from air onto ZnSe with θ=tan-1(NR) = 71.6°, What is the refraction angle of the transmitted wave? B) Calculate the magnitude R and phase shift ψ...

Sorry, I'm still not getting it, I don't understand what I'm taking the Fourier transform of.

Can you clarify on how to change it to shifted Gaussian function? Another question. Since it's not specified, what limits of integration do i take? I only assume it is -a/2 to a/2, from other examples I've seen.

Homework Statement A very large diffraction grating has an amplitude transmission aperture function A(x) = 1/2[1+cos(kx)]e^(-x^2/a^2) a) What is the far-field irradiance diffraction pattern when a >>1/k B) Plot the pattern c) Using the appropriate resolving criteria, find the grating's...
