'In many ways, the manufacturing strategy is helping us redefine and reinvent how we do business in General Motors,' said Scott Whybrew, GM's executive director of global manufacturing engineering.
When the phase shift is exactly Â±90Â°, then circular polarization is produced (fourth and fifth figures). Thus is circular polarization created in practice, starting with linearly polarized light and employing a quarter-wave plate to introduce such a phase shift.
Where the absorption of light circularly polarised in one direction (right-handed) is different from the absorption of the light circularly polarised in the opposite direction (left-handed), the material is said to exhibit circular dichroism.
