Webpolarization is uniform so that clearly ∇·P = 0, and hence the volumetric bound charge density ρb = 0. The surface bound charge density ρs b = n· P is nonzero, however. Now, in the spherical coordinates (r,φ,θ), where φ and θ are the azimuthal and inclination angles respectively, the unit normal vector is n = (cosφsinθ,sinφsinθ ... Weba) The bound volume charge density is ρ b = − ∇ →. P → = − ∂ ∂ z P 0 = 0 Since P 0 is a constant. The bound surface charge density of a surface with the outward normal n ^ (unit vector) can be obtained as σ b = P →. n ^ The flat surface of the hemisphere is in the xy plane. Hence the outward normal to this flat surface would be − z ^.
