1. (a) (2 points) For a transmission line circuit, what is the smallest distance d from the load for which the input impedance is the same as the load impedance Zn = 2L? (i) dmin = 1/8 (ii) dmin = X/4 (iii) demin = X/2 (iv) din (b) (2 points) For a transmission line circuit, what is the smallest distance d from the load for which the input voltage is the same as the voltage at the load Vin = V.? (i) denin = X/8 (ii) dmin = X/4 (iii) dmin = X/2 (iv) dmin = (e) (2 points) Consider the following statements about voltage standing wave ratio (VSWR): i. The VSWR for a lossless transmission line is equal to the normalized impedance value on the constant || circle crossing the real axis on the right side on a Smith Chart. ii. On a lossless transmission line with characteristic impedance Zo, terminated with a purely short circuit load, VSWR = 1. (1) Both are false (ii) Only (i) is true. (iii) Only (ii) is true (iv) Both are truc. (d) (3 points) An infinite static current sheet with J. = 2% (A/m) is located at y = 1 (m), and another sheet with J. = 22 (A/m) is located at a = 1 m. What is the magnetic field at the origin? (i) 22 (ii) -22 (iii) -29 - 22 (iv) ý +7 (v) -ý - 2
