Question: The ratio J/Jd (conduction current density to displacement current density) is very important at high frequencies. Calculate the ratio at 1 GHz for: (a) Distilled

The ratio J/Jd (conduction current density to displacement current density) is very important at high frequencies. Calculate the ratio at 1 GHz for:
(a) Distilled water (μ = μo, ε = 81εo, a = 2 X 10–3 S/m)
(b) Sea water (μ, = μo, ε = 81εo, a = 25 S/m)
(c) Limestone (μ. = μo, ε = 5εo, σ = 2 X 10–4 S/m)
