Full and rigorous vector diffraction model for a multilayered optical disc.
A full and rigorous vector diffraction model for a multilayered optical disc is described where three vector diffraction processes, namely the focus of the reading light, the interaction with bits and the detection part, are all considered. Moreover, the reflected electric fields resulting from the infinite number of bounces at the multilayered optical disc are also involved. As an example, the detected power is calculated when the reading spot is scanned over the disc under the case of the circularly polarized illumination.
