Standard Properties
| Name | Default value | Default unit | Range |
|---|---|---|---|
beam direction The direction of the propagation. |
2D Z normal | - | [2D X normal, 2D Y normal, 2D Z normal |
frequency Central frequency of operation. |
193.1 | THz* *std. unit is Hz |
(0, +∞) |
waist radius The 1/e field (1/e2 power) radius of the beam. |
10e-006 | m | (0, +∞) |
distance from waist The distance from waist. A positive distance corresponds to a diverging beam, and a negative sign corresponds to a converging beam. |
0 | m | (0, +∞) |
refractive index The refractive index of the homogenous material in which the Gaussian beam is found. |
1 | - | (-∞, +∞) |
theta The angle between the normal-axis and the direction of propagation. |
0 | rad | (-∞, +∞) |
phi The angle between the direction of propagation and the horizontal-axis. |
0 | rad | (-∞, +∞) |
polarization angle The polarization angle is defined with respect to the horizontal-axis for normal incidence fields. When the incidence is off-axis, the polarization angle should be '0' for p-polarized light and 'pi/2' for s-polarized light. |
0 | rad | (-∞, +∞) |
