Consider the interface between a conductor and air. This interface forms a surface planar in 2D parallel to the axis of Z. In the diagram, one could see that the interface passes to through the points (3,0,0) and (0,4,0). The origin is located in the conductive region. Permittivity air is ?o. has. Determine the unit vector n that is normal to the interface pointing in the direction of the dielectric region b. Determine the electric field (vector) near the interface in the dielectric region if the amplitude of the Y component is E = 25 V/m. In other words, use the conditions at the appropriate interfaces to determine the X and Z components of the electric field E = (Ex + 25y+ Ez) V/m.
