CHIRALITY IN OPTICAL FIELDS
KEY to Table Symbols:
- 1-DE with left orientation (l) top This is sometimes
referred to as 'Left Hingeing'
- 1-DE with right orientation (r)bottom This is
sometimes referred to as 'Right Hingeing'
- External arrows: denote spin chirality of field.
A=anticlockwise, C=clockwise, N=neutral.
- Internal arrows: denote inclination of elements to
field centre. f=centrifugal, p=centripetal, n=neutral
Permutation Table of fields derived from left and right oriented
If a field is either an [N] or an [n] type the effect is the same
for fields composed of elements that are either 'left oriented' or 'right
so that using (l) and (r) hingeing there are a total of 16 types of
field. When the actual field effects are analysed it is found that 8 types
as the chirality of the 1-D elements can be discounted except at very
close range. Then it becomes merely a matter of field diameter for the
number of elements in the respective field
