  2. z-z z z+z Telegraphist's equations

  3. w d D z strip line

  4. Time harmonic excitation movie

  5. z-z z z+z Wave equation

  6. z-z z z+z Wave equation k is the wave number

  7. z-z z z+z Wave equation

  8. z-z z z+z Wave equation current wave

  9. z-z z z+z characteristic impedance

  10. z-z z z+z characteristic impedance

  11. w d D z strip line

  12. w d D z strip line

  13. D z a b coaxial cable

  14. a = 3 mm b = 6 mm coaxial cable

  15. D D z a twin lead

  16. w d D z D z a b D D z a summary

  17. w d D z D z a b D D z a summary

  18. terminations standing wave VSWR

  19. -z Help! terminations Zc ZL z = 0 Why?

  20. -z Zc ZL z = 0 terminations

  21. -z Zc ZL z = 0 terminations normalized impedance

  22. -z Zc ZL z = 0 reflection coefficient

  23. Pulse propagation from one transmission line to another

  24. Pulse propagation from one transmission line to another

  25. -z Zc ZL z = 0 reflection coefficient 3 special cases "short" "matched" "open"

  26. -z Zc ZL z = 0 Incident plus reflected waves. Incident plus reflected waves. reflection coefficient

  27. R = -1

  28. Standing wave movie

  29. R = +1

  30. standing wave R = +1 R = -1 -z z = 0

  31. VSWR

  32. Let us examine other values of the reflection coefficient.

  33. probe w narrow slit d D z

  34. D z a probe narrow slit b

  35.  2 1.5 1 Minimum deflection Maximum deflection Zc ZL z = 0 -z

  36. Phase shift in the reflection coefficient

  37. l 1 + |R| 1 - |R|

  38. -z Zc ZL z = 0 Incident plus reflected waves. Incident plus reflected waves. reflection coefficient

  39. -z Zc ZL z = 0 impedance along the line

  40. -z Zc ZL z = 0 impedance along the line

  41. -z Zc ZL z = 0 impedance along the line

  42. -z Zc ZL z = 0 impedance along the line

  43. -z Zc ZL z = 0 impedance along the line

  44. -z Zc ZL z = 0 impedance along the line Look at a distance z = - L toward the generator

  45. -z Zc ZL z = 0 impedance along the line impedance is periodic every half-wavelength

  46. -z Zc ZL z = 0 impedance along the line quarter wavelength Z <==> Y short ==> open open ==> short

  47. -z quarter wave transformer Zc1 Zc2 ZL z = 0 matching frequency sensitive

  48. -z Zc ZL z = 0 shorted line open line all values of reactance

  49. L X = Zc tan kL

  50. Should I add something in series or in parallel?
