Question

The figures described by the tip of the eleetrie veetor with time for different plane waves on one of its wavefront surfaces are shown in igure 1. Note that the last value of the instantaneous field is highlighted by their components on X and Y axis. Polarization I Polarization Il Polarization III Polarization IV Figure 1: Polarizaciones.

Figure 1: Polarizaciones. Indicate (explaining your reasonimg) to what hgure (1, 11, I1l, IV), if any, corresponds each one of the following fields given either in time or phasor form: a) E{t) = cos(t)f + cos(ut +i b) E(t) = sin(wt +i + cos(wt + ) c) E -eii +e7ij d) E =f+eJij e) Et)= cOs(uwt)f - in(wt)j 1) E i+eÅj g) E=ei+eiëj h) E=i -eij i) E = e7i +ý Note that it could be the case that one of the expressions a-i given above does not correspond to any of the cases shown in igure 1. Also, it may be that some of the polarizations shown in figure l would not have correspondence with any of the expressions a-i given above.

Answer 1

Need more information about polarization.
