Reconsider the two-layer dielectric in Questions 1. An alternating voltage of sinusoidal waveform is applied to it. The frequency () dependence of the real (K()) and imaginary (K()) parts of the two-layer dielectric is given by the Debye equations K()=K{1+1+22k}K()=K{121+1+22k}, where K is given by K=Co(R1+R2)12 while k is given by with k=12(1+2)12=1d2+2d11d2+2d1 (a) What is the relaxation frequency of space charge polarization of the BTO-TO two-layer capacitor? (b) Plot the variation of K() with frequency (). (c) Plot the variation of K() with frequency (). (d) Plot the variation of loss tangent (tan) with frequency () where tan is defined as tan(())=K()K()
