3. A lossy dielectrics (conductivity = σ, absolute permittivity = ε) is placed between two parallel perfect metal plates, as shown in the figure below. The areas of the metal plates are A (A = W×L). The distance between the metal plates is d and is much smaller than the length or width of the metal plates (d ＜＜ W and d ＜＜ L). Applying a voltage V₀ between the perfect metal plates, please evaluate the ratio between the storage energy and dissipated power of this structure (E_storage/P_diss).
