ELEG 320 ELECTROMAGNETIC FIELD THEORY I HOMEWORK #5 – DUE NOVEMBER 4, 2010 1. 2.27 (6 th Edition) 2.17 5 th Edition 2. Starting from the Telegrapher’s equation (Transmission Line Equations) derive the equations for wave propagation on transmission lines. 3. 2.18 (6 th Edition) 2.11(5 th Edition) 4. A parallel plate transmission line is made up of perfect conductors of width ± ²³´ and lying in the planes µ ± ¶·¸¹º·µ ± ²¶³´ . The medium between the conductors is a nonmagnetic perfect dielectric. For a uniform plane wave propogating along the line, the voltage along the line is given by. »¼½¾ ¿À ± ³¶ ÁÂüÄÅ Æ ³¶ Ç ¿ È ÉŽÀ ·» Find a) The electric field intensity Ê Ë ¼½¾ ¿À· of the wave; b) The magnetic field intensity Ì Í ¼½¾ ¿À of the wave; c) The current μ½¾ ¿À along the line; and d) The power flow ϼ½¾ ¿À down the line 5.

Unformatted text preview: long coaxial cylindrical conductors. Also show that the power flow along the line is equal to the product of the voltage between the conductors and the current along the conductors. 6. 2.3 (6th Edition) 2.4 (5th Edition) 7. A network N consists of a single circuit element ( R , L , and C ). The system is initially uncharged. The switch S is closed at t = 0, and the line voltage at z = 0 is observed to be as shown the figure below. Determine whether the circuit element is R , L , or C , and find the value of Z 02 / Z 01 . 8. In the system shown below, the switch S is closed at t = 0. The line voltage variations with time at z = 0 and z = l for the first 5 μs are observed to be as shown in the graphs below the system. Find the values of V , R g , R L , and T ....
