推 cch0927:(a)應該是橢圓 (b)合成後長度一樣即為圓偏振! 02/03 20:54
→ cch0927:所以(C+1)^2+(2C)^2=5 02/03 20:56
Consider two electric fields given by
_ _ _ _ _ _ _ _
E1 = Cax+Cay+azcos(ωt-βz)，E2 = ax+Cay-2azsin(ωt-βz)
_ _
(a). Find the polarization of E1+E2 for C=2
(b). Find the value of C for which E1+E2 is circularly polarized.
不會看，煩請高手
