Question4: a. Why do we study Boundary Conditions? Also, Determine the boundary conditions equations (for \( \mathrm{E} \) and \( \mathrm{D} \) ) if you have free space that meets with a dielectric medium (Figure 2). a. Prove that: \( Q_{e n c}=\frac{\varepsilon}{\sigma} \int J \cdot d s \quad \) (Hint: use Gauss's and current density laws)
