Tutorial#12 (Q1] The x-y plane at z = 0 is a charge-free boundary separating two dielectric media with permittivities & and €. If the electric field in medium 1 is E, = Ex +ý Ey +2 Ex, find the electric field E, in medium 2 [02] A uniform electric field intensity of E =-2, +4a, -6a, kV/m exists at 2 <0, with the interface separating two homogeneous dielectrics on the xy-plane at z=0. The electric permittivity for medium 1. € -6 at 2<0; and for medium 2. ,,=8 at z>0. Determine: (a) The normal and tangential components of E, (b) The electric flux density of medium 2, D. at 220 103) A dielectric slab, with a thickness of 6 cm and dielectric constant of 4, is sandwiched between two different media; free space to the left and another dielectric, with a dielectric constant of 9, to the right. If the electric field in th the free-space medium is E = 2a, +4a, - 6a, kV/m Determine: (a) The normal and tangential components of E, E2 and E3 (b) The electric flux density of medium 2. D. and D3 (94) With reference to Fig. 4-19, E, = 83 - 92 +2239 = 23,6 = 1869, and the boundary has a surface charge density p. = 3.54 x 10-1S 3. What is E/? b. What angle does Emake with the z axis?
