HOMEWORK ASSIGNMENT 4 DATE: OCTOBER 19, 2011 DUE DATE: OCTOBER 26, 2011 SUBJECT: ADVANCED ENGINEERING ELECTRODYNAMICS (EE260A) INSTRUCTOR: PROF. YAHYA RAHMAT-SAMII 1. Read course notes and related sections of chapters 6 of Prof. Balanis’ book. (10 points) 2. Complete the steps needed to get equations (6-107), (6-107a) and (6-108a) in Prof. Balanis’ book. (20 points) 3. Scattered far field by a PEC rectangular plate: (a) Carefully repeat the steps presented in Example 6-5 of Prof. Balanis’ book. (b) Construct the scattered patterns both in normalized amplitude and in dB scale for incident angles of 0 and 45 degrees for the same plate dimensions as in the example. (c) Plot the 3D pattern (if you can) and 2D patterns along the length direction (x direction), width direction (y direction), and diagonal direction. (d) Compare the results and discuss your observations such as 3-dB beam width and beam directions. (e) If you have time you may want to use one other set of dimension and incidence angles of your choice and repeat the above steps. You may have to write a short computer program to do this. Include a copy of your programs as

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.
