Determine E i , Di and P i inside the lucite. Lehigh University Power Systems Engineering Master's and Certificate available OPEN engineering.lehigh.edu Step-by-Step Report Solution (https://holooly.com/report-a-problem/) Verified Solution We assume that the introduction of the lucite sheet doe not disturb the original uniform electric field E o The situation is depicted in Fig. 3-17. Since the interfaces are perpendicular to the electric field , only the normal field components need be considered. No free charges exist. Boundary condition Eq. (3-77) at the left interface gives Di = ax Di = ax Do , or Di = ax ϵo E o . There i no change in electric flux density across the interface. The electric field intensity inside the lucite sheet is E i = 1ϵ Di = 1 ϵo ϵr (https://holooly.com) Eo Di = ax 3.2 Hence the effect of the lucite sheet is to reduce electric intensity. The polarization vector is zero outside the Iucite sheet (P o P i = Di − ϵo E i = ax (1 − = ax 0.6875ϵ0 E o = 0). Inside the sheet, 1 3.2 ) ϵo E o (C/m2 ) Clearly, a similar application of the boundary condition Eq. (3-77) on the right interface will yield the original E o and D o in the free space on the right of the lucite sheet. Does the solution of this problem change if the original electric field is not uniform; that is, if E o = ax E(y)?
