The three regions shown in figure are all lossless and non-magnetic. Find.
- Wave impedance in mediums $2$ and $3$.
- $d$ such that medium $2$ acts as a quarter wave $(\lambda / 4)$ transformer.
- Reflection coefficient $(\Gamma)$ and voltage standing wave ratio $\text{(VSWR)}$ at the interface of the mediums $1$ and $2$, when $d=\lambda / 4$.
