Homework Statement
The aperture has vertical opaque strips of width, a, separated by open spaces of width 2a. The width of the overall aperture is L = 19a.
a) Write a transmission function for this aperture.
b) What would the field distribution be, at a plane in the Fraunhofer zone, if the aperture was
irradiated by a plane wave directed along the normal of the aperture? Draw a sketch of the
irradiance pattern along the X and Y axes of the far field plane.
---------------------------------------------------------
Despite searching through some notes and several textbooks I still cannot find a clear expression for a transmission function that includes the specifics of this question. If someone can help or make some useful references that would be very helpful, thank you.
