Worth 5 points: From “The Story of an Hour” by Kate Chopin, what does the revelation Louise Mallard has when locked in her bedroom say about Kate Chopin’s opinions regarding the institution of marriage? Further, how does Chopin feel about women and their role in society? How do Chopin’s ideas differ from 19th-century tradition? Your answer should be at least 4-6 sentences in length.

Both problems of this test concern solving the electromagnetic bandstructure master equation: ∇×[ϵ−1(∇×H)]=(ωc)2H{“version”:”1.1″,”math”:”\[\nabla \times [{ \epsilon ^{ – 1}}(\nabla \times H)] = {\left(\frac{\omega }{c}\right)^2}H\] “} 1. Consider a square lattice of square rods of variable width Sb{“version”:”1.1″,”math”:”\(S_b\)”} (in units of a{“version”:”1.1″,”math”:”\(a\)”}), in a medium of dielectric constant ϵ=13{“version”:”1.1″,”math”:”\(\epsilon=13\)”}, similar to the structure depicted below. Figure 1: A square lattice of square rods of dielectric constant ϵ=12.25{“version”:”1.1″,”math”:” \(\epsilon=12.25\) “}(blue). The TE band-diagram and the TM-band-diagram is as follows: Figure 2: (Left) TE band gap atlas for Fig. 1. (Right) TE band diagram for Fig.1. Both were calculated using MIT Photonic Bands (MPB). 1a. Using output from the diagram, fill in the following blanks: The first TE bandgap range is fromf=―to―{“version”:”1.1″,”math”:” \(f=\underline{\hspace{2cm}} to \underline{\hspace{2cm}}\)”}c/a{“version”:”1.1″,”math”:”\(c/a\)”}. 1b. The minimum TE bandgap is seen for values of Sb{“version”:”1.1″,”math”:”\(S_b\)”} between ―to―a{“version”:”1.1″,”math”:”\(\underline{\hspace{2cm}} to \underline{\hspace{2cm}} a\)”}. 1c. The maximum TE bandgap is seen for \(S_b= \underline{\hspace{2cm}}\)\(a\). 1d. Decreasing the square rod lattice \(\epsilon\) to 6 would have what major effects on the bandgap frequencies? \(\underline{\hspace{2cm}}.\) 2. Consider the band diagram for a square lattice of square rods depicted in Fig. 1 with a defect line of missing rods, as depicted below in Fig. 3. Figure 3: Square lattice of square rods with a defect line of missing rods. 2a. Using output from the diagram, fill in the blanks: The first TE bandgap range is from \(f=\underline{\hspace{2cm}} to \underline{\hspace{2cm}}c/a\). 2b. What is the frequency of the TE defect mode in reduced units at the \(\Gamma (k=0)\) point? 2c. How does its dispersion behave with wavevector, and why? 2d. What would happen to the TE defect mode frequency band if one were to use \(\epsilon=16\) for the defect rod, and why? Congratulations, you are almost done with Exam 1.
