A dielectric slab, with a thickness of 6 cm and dielectric constant of 4, is sandwiched between two different media; free space to the left and another dielectric, with a dielectric constant of 9, to the right. If the electric field in the free-space medium is at an angle of 30 at a height of 3 cm at the leading interface, as shown in the figure below, determine the: (a) Angle a (in degrees, as measured from the normal to the interface) the electric field will make in the dielectric medium to the right of the center slab. (b) Height h (in cm) the electric field will have at the trailing interface. (c) Assume the incident electric field is vertically polarized, is there a new incidence angle that will cause total transmission between the second and third dielectric boundary? 3 cm Free space = 4 8,= 9 = ? 30 h = ? 6 cm- A dielectric slab, with a thickness of 6 cm and dielectric constant of 4, is sandwiched between two different media; free space to the left and another dielectric, with a dielectric constant of 9, to the right.
