μ/ε  mo E - v × μH MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Electrical Engineering and Computer Science 6.013 Electromagnetics and Applications Quiz 1 Solutions Problem 1. (34/100 points) E = 2 ˆ x cos(t + z) and H = ˆ y sin(t z ) 2  . a) z (t z) 0 velocity v 1 [m/s] tt      b) Wave intensity I = 22 E H 2cos (t) 1 [W/m ] c) η = E/H = 2. μ = η/v = = 2×1 = 2 [H/m] d) Pressure P m = W m = 2 1 H 2 where |H| = 2 at s = ∞ . P m = 2 1 2 4 = 2 [N/m 2 ] Problem 2. (18/100 points) f e = -e( ) = 0 E y = -v m B. But V = E y W   v m = - E y /B = - V/WB Problem 3. (20/100 points) H // is continuous since = 0   J s
