  1. Edward C. Jordan Memorial Offering of the First Course under the Indo-US Inter-University Collaborative Initiative in Higher Education and Research: Electromagnetics for Electrical and Computer Engineering by Nannapaneni Narayana Rao Edward C. Jordan Professor of Electrical and Computer Engineering University of Illinois at Urbana-Champaign Urbana, Illinois, USA Amrita Viswa Vidya Peetham, Coimbatore July 10 – August 11, 2006

  2. 6.1Transmission Line

  3. Parallel-Plate Line Neglect fringing (d << w).

  4. Consider the circuit

  5. Then Transmission Line Equations

  6. Transverse Electromagnetic (TEM) Waves

  7. Distributed Equivalent Circuit Assumes perfect conductors but lossy dielectric.

  8. Transmission-Line Equations L = Inductance per unit length (H/m) C = Capacitance per unit length (F/m) G = Conductance per unit length (S/m)

  9. In general, conductors are also lossy. Then, the waves are not exactly TEM waves. R = Resistance per unit length (/m)

  10. Lossless Line (Perfect Conductors, Perfect Dielectric) Combining, we obtain Wave Equation

  11. Solution:

  12. Thus

  13. Parallel-Plate Line

  14. Coaxial Cable

  15. Parallel-Wire Line

  16. Parallel-Strip Line (d/w 1) imbedded in a homogeneous medium

  17. Microstrip Line

  18. Shielded Strip Line
