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...
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...
