3. Fraunhofer Diffraction II: Consider a rectangular aperture with a rectangular obstruction defined as follows: $P(x, y) = \text{rect}\left(\frac{x}{L}, \frac{y}{L}\right) - \text{rect}\left(\frac{x}{S}, \frac{y}{S}\right)$ where $L = 1cm$, $S = 0.5cm$. (a) Calculate and sketch/plot the Fraunhofer diffraction pattern (intensity) at a distance $z$ from the aperture when the aperture is illuminated by a unit amplitude monochromatic on-axis plane wave: $u_{in}(x, y) = 1$ of wavelength $\lambda = 1\mu m$. Use the propagation distance $z$ where Fraunhofer diffraction approximation becomes valid. [20 points] (b) Repeat (a) with $S = 0.9cm$. [10 points]
