3. A plane wave with $\vec{E}_i(z) = \hat{a}_z E_0 e^{-j\beta_1 z}$ $\vec{H}_i(z) = \hat{a}_y \frac{E_0}{\eta_1} e^{-j\beta_1 z}$ is normally incident upon the interface at $z = 0$, as shown in the figure. The reflected and transmitted fields are in the form $\vec{E}_r(z) = \hat{a}_z \Gamma E_0 e^{j\beta_1 z}$ $\vec{H}_r(z) = -\hat{a}_y \Gamma \frac{E_0}{\eta_1} e^{j\beta_1 z}$ $\vec{E}_t(z) = \hat{a}_z \tau E_0 e^{-j\beta_2 z}$ $\vec{H}_t(z) = \hat{a}_y \tau \frac{E_0}{\eta_2} e^{-j\beta_2 z}$ a) Using the boundary conditions, derive the expressions for the reflection coefficient $\Gamma$ and transmission coefficient $\tau$ in terms of the intrinsic impedances $\eta_1$ and $\eta_2$. b) Now given that $\mu_1 = \mu_2 = \mu_0$ and the magnitudes of the reflection coefficient and transmission coefficient are given as $|\Gamma| = 0.5$. $|\tau| = 0.5$ calculate $\epsilon_2/\epsilon_1$.

Write a program to solve the Skyline problem O(n log n) time. You should write a program but it should run in time O(n log n). We will provide input as a sequence of triples each on a line. You provide the output as a sequence of doubles each on a line. Input format is three non-negative numbers where the first number is the starting location, second number is the height and the third number is the ending location. Third number is greater than equal to the first number. Write a full python program with O(n log n) for the same.

2. In an orthogonal metal cutting test, the following information is available: Cutting Force = 900 N, Thrust Force = 900 N; Width of cut = 2.5 mm, Thickness of the workpiece before cut = 0.25 mm, Chip thickness (after cut) = 1.0 mm; Chip-tool contact length on tool's surface (Rake Face) = 0.5 mm; Tool Rake angle (inclination of the tool rake face): -5 degrees (5 degrees on the negative side). Draw the Force Circle at the tool's cutting point/edge and show on the drawing tool's negative rake angle, the shear plane angle, the friction angle, and all the force vectors in the Force Circle. Calculate: Shear plane angle; Friction angle; Mean Shear Stress on the Shear Plane; Mean Frictional Stress on the Tool Rake.
