The boundary between two materials is the xr = Material 1, which has a dielectric constant of 2. The x < 0 region is filled with Material 2, which has a dielectric constant of 5. There is no free charge on the x =0 plane. If the electric field intensity in Material 1 is E-(10,-20, 15) V/m, determine E2. 0 plane. The x > 0 region is filled with

Recall the boundary conditions on static E and B at an interface between two materials: E, and B are always continuous, and H is continuous in the absence of free surface current. What boundary condition(s) does this imply for S? Do they make physical sense? An explanation is required.
The space between the plates of a parallel-plate capacitor, shown below, is filled with two slabs of different dielectric materials
Problem 5 The space between the plates of a parallel-plate capacitor, shown below, is filled with two slabs of different dielectric materials. The slab at the top has thickness 2d and a relative dielectric constant of er1 = 3 and the one at the bottom has thickness d and a relative dielectric constant of er2 = 2. The capacitor plates have surface area S. a. Assume a total charge of +Q on the top plate and -Q on the bottom plate. Find...

3) Consider a circularly polarized light reflecting from a boundary between two dielectric materials characterized by & and E2. (a) Assume the incident light is normal to the interface (0-0) will the reflected wave be circularly polarized? (b) Assume r < E2 and >0 will the reflected wave be circularly polarized? (c) Assume eE2 and 0> 0c so there is total internal reflection. Will the reflected light be circularly polarized?

1. For the given capacitor, there are conducting plates at z = 0 and 2 = 3d. Between the plates, there are 3 layers of insulators: 2 free space regions and one dielectric with permittivity e. The electric field in Region 1 is E = - a, (V/m), where Ps is the surface charge density on the top plate ( = 30). The surface area of each plate is A. (a) What...

5. (20 points) For many dielectric materials, the relationship between the displacement field D and the electric field E in the material is linear and can be represented simply by th equation D-eE, where ε is the permittivity of the medium. Consider now two long, co- axial cylindrical conducting shells separated by such a dielectric (see the cross-sectional figure below). Let the surface charge density on the inner cylinder with radius a be +o, and assume that the charge is...
