a) Determine the polarization of the following wave: H_{s}=12 e^{j m / 3} e^{-j 10 x_{\mathrm{A}}}+5 e^{-j \pi / 3} e^{-j 10 x_{\mathrm{a}}} \mathrm{A} / \mathrm{m} Choose the correct option:

Distortionless TLs are usually recommended for use as these – (i)are lossless. (ii)are constant phase lines. (iii)can offer a constant loss that is independent of frequency. (iv)are cheap. (v)are discussed in the course syllabus.
