Reciprocity relations for s-p polarization conversion in conical diffraction
We derive symmetry relations for the coefficients describing cross polarization in light diffracted from gratings used in conical mountings. We use the reciprocity theorem to show that, for a given angle of incidence, the fraction of s or p polarized incident power that changes its polarization upon...

| Sumario: | We derive symmetry relations for the coefficients describing cross polarization in light diffracted from gratings used in conical mountings. We use the reciprocity theorem to show that, for a given angle of incidence, the fraction of s or p polarized incident power that changes its polarization upon specular reflection, does not depend on the polarization of the incident wave. It is shown that under certain conditions of incidence this property also holds for non-specular orders. Numerical computations for cycloidal, triangular and sinusoidal gratings illustrate these symmetry relations. © 1995. |
