Write a MATLAB code:

In the given set-up, plot the E fields inside both dielectrics if a. No charge is present in the interface. b. Charge is present in the interface (p, is nonzero of your choice) E = 3 E = -2xf - y (0. 0) c. Plot the magnitude of E fields (JE|) at each points in question 1(a). ( Change the values of dielectric constants in both layers and plot J|. Explain your observation.) Ez = 6
