Homework #..........; Due, .................................... (before beginning of class).
1:  Problem 11.26
a:  As stated in the book
b:  As stated in the book

Homework #...; Due, ......................................... (before beginning of class).
  For the scattering of a plane wave by a PEC sphere of radius a, with the incident electric field with only one component (Ex-incident), as outlined in Section 11.8 in our text book:
1:  Derive an expression, in simplified form, for the cross-polarized component (Ey) of the far-zone scattered electric field in the monostatic direction only.
2:  Derive an expression, in simplified form, of the 3-D monostatic RCS for the cross-polarized field.
3:  Plot the normalized RCS (RCS/pi x a^2) for 0 < a < 2 lambdao(free space); similar to Figure 11-26 in the textbook:
a:  Dimensionless
b:  In dB
  If you have any comments to make concerning the monostatic cross-polarized field and associated RCS, please do so.
