A parallel plate capacitor is composed of two lossy media with relative dielectric constant &ri 12 and 82 3.5, and thickness di 1.5mm and d 3.5mm. Lossy nature manifests itself through a steady-state leakage current with the normal component Jn flowing across the interface between the two dielectric media which have electrical conductivity o1 2x 10-3 and a2 = 5 x 104 S/m, respectively. The two media have dielectric strength EMaxt = 60 MV/m and EMax2 25 MV/m respectively, where...
