EECS 117A, Midterm #2, Fall 1998 EECS 117A, Fall 1998 Midterm #2 Professor S.E. Schwarz Problem #1 (40 points) We want the four S-parameters for the block shown above. Use the notation shown. The reference impedance is 50 ohms. (a) Find S 11 (b) Find S 22 (c) Find S 21 (d) Find S 12 Problem #2 (30 points) Consider a thin, rigid, spherical shell of material centered at the origin. The shell occupies the space between r = a and r = a+h, and you should assume h << a. The shell has a uniform charge density rho , and it rotates around the polar axis (or z-axis) with angular velocity omega radians/sec. Find the magnitude | H | of the magnetic field at the origin. (If you happen to get an integral that you can't evaluate, just leave it in the form of an integral.) (1 of 2)1/27/2007 4:28:56 PM

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
