Heterogeneous Medium Models (60 pts). a) In the notes on Heterogeneous Media, show that equation (*) satisfies the appropriate boundary conditions, and perform the calculations needed to obtain the results (**) and (***). b) Given the Bruggeman effective medium approximation in 3D, - eff +20 +42 eff 02- eff 02 +20 = 0 eff and setting = 2 =1-0, solve for eff. You should get an expression involving square roots. Show that, for o <
