1. EEE340Lecture 361 The magnetic field The total magnetic field Note: The Eq. above doesn't work for summation of two waves! (8-103)

2. EEE340Lecture 362 Time domain results Zeroes of E 1 (z,t) Maximum of H 1 (z,t) Zeroes of E 1 (z,t) Occur at

3. EEE340Lecture 363 Traveling wave versus Standing wave In time-domain, location r or location r and time z and time t in the phase t are decoupled are coupled In phasor form or sin kz or cos kx

4. EEE340Lecture 364 8-8 Normal Incidence at Plane Dielectric Boundary Configuration

5. EEE340Lecture 365 Boundary Conditions tan E continuous tan H continuous

6. EEE340Lecture 366 Immediately The total field in medium 1 is 1. maximum occurs at 2. Standing wave ration(SWR) (8-142) (8-143) (8-144) (8-145) (8-147)

7. EEE340Lecture 367 Example 8-11 A uniform plane wave in lossless medium of  1 is incident normal on lossless medium  2. Obtain the time-average power in both media. Solution: In medium 1, (8.96) (8.144) (8.131 & 8.133)

8. EEE340Lecture 368 Hence ( 8.152 )

9. EEE340Lecture 369 In medium 2 Since (8.153) (8.155)
