Momentum Density Associated with EM Waves Linear momentum per unit volume: P = μ₀ε₀E × B Angular momentum per unit volume: L = (rxP) = μ₀ε₀(rxE × B) Notes: Page 59 Page 763 Page 760 Page 765 K* = (20π + 750i) m^-1 K* = α + iβ Given: α = 20π β = 750 m^-1 δ = 1/β = 1000/750 mm = 1.33 mm Conditions: σ >> εω σgood = √(εω/σ) Equation: E(z,t) = (E₀e^(-αz)) * cos(βz - ωt) Calculations: β = 1/3a α = √(1/3)a δ = 1/β = 3a φ = tan^(-1)(β/α) = tan^(-1)(√3) = 30° v = ω/α = ω√3a Phase difference between E and B: Vacuum: φ = 0 Dielectric: φ = 0 Poor conductor: φ = π/2 Lossy dielectric: φ = tan^(-1)(K*ε/ω)
