Angle-Dependent Fresnel (s & p) calculator
s- and p-polarized reflectance/transmittance at any incidence angle.
Category: Materials
Formula: rs, rp from cosθi, cosθt · R = |r|²
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| n1 | n1 | 1 | |
| n2 | n2 | 1.5 | |
| Angle θi | th | deg | 45 |
Result with the default inputs
- Rs: 9.201 %
- Rp: 0.847 %
- Ravg: 5.024 %
Open it with your own values: put each input in the address as a parameter, for example /calculators/angle-dependent-fresnel-s-p?n1=1. A unit other than the listed one goes in <parameter>_unit.
