Ae =Wm/W(r)max=1/W(r)max∫ ∞−∞∫ ∞−∞W(r) dA W(r) =1/2{︃Re [︃dε(r)ω/dω]︃|E(r)| ^2 + µ0|H(r)| ^2} where ω is the angular frequency, ε(r) is the profile of relative permittivity, µ0 is the permeabilityin vacuum, and |E(r)|^2and |H(r)|^2are the intensities of the electric and magnetic fields,respectively.
