Electromagnetic vector-sensor (EMVS) has been ...to consist of partially polarized or fully polarized light. The polarization of a light beam can be represented by its electric field vector. Its optical power is a scalar quantity that is proportional to the mean square of the electric field amplitude. Let z be the direction of propagation. Then, the polarization vector is in the x-y plane.By convention, the "polarization" direction of an electromagnetic wave is given by its electric field vector. Considering a monochromatic plane wave of optical frequency f (light of vacuum wavelength λ has a frequency of f = c/λ where c is the speed of light), let us take the direction of propagation as the z axis. Sep 16, 2021 · The polarization vector here represents the direction of the electric field. In this problem, it is $\hat{\mathbf{z}}$ for all three lasers. It's important to consider here since field amplitudes will add; in the middle, the polarization vector allows us to see that the electric field contributed by each laser is the same, and will add accordingly. an Note that even for some small volume ∆ v , there are many atoms/molecules present; therefore there will be many electric dipoles. E ( r ) We will therefore define an average dipole moment, volume, called the Polarization Vector P ( r ) . per unit where pn is one of N dipole moments in volume ∆ v , centered at position r .The vector equation of a line is r = a + tb.
