11. Where the plus sign indicates right circular polarization and the minus sign indicates left circular polarization . 12. Where the plus sign indicates left circular polarization and the minus sign indicates right circular polarization. 13. Where the plus sign indicates left circular polarization and the minus sign indicates right circular polarization . 14. For instance, back scattering of radar pulses by rain drops can be avoided by using circular polarization . 15. This radar uses radio waves along with horizontal, dual ( horizontal and vertical ), or circular polarization . 16. For instance, a quarter-wave plate is commonly used to create circular polarization from a linearly polarized source. 17. He demonstrated the circular polarization of cinnabar. 18. This DOE is generated by a circular polarization of the depletion laser, combined with a helical phase ramp. 19. Most Ku-band transponders use linear polarizatoin ( H and V ) ( Some C-band transponders use circular polarization . 20. In the case of circular polarization , the electric field vector of constant magnitude rotates in the x-y plane.
